My research mostly focusses on the formation
and evolution of stars and their planetary systems. In particular
I am interested in the dusty debris material that surrounds some stars,
including the Sun, during their main sequence phase. The dust is heated
by the star and is observed by its thermal emission in the mid-IR to
sub-mm; this thermal emission is detected either as an excess above the star's
photospheric emission or as emission that is extended from the
otherwise point-like star. In the few (6 as of 12/9/00) cases where the dust
emission has been mapped, it is seen to lie in a disk around the star. It is
thought that in much the same way that the disk of dust in the solar system,
i.e., the zodiacal cloud, is created by the break-up of the solar system's
asteroids and comets, this exozodiacal dust is also the end product of the
break-up of the remnants of the system's planetary formation phase. As Vega was
the first main sequence star other than the Sun that was shown to
exhibit infrared emission in excess of its photospheric emission, stars with
similar excesses are known as Vega-type stars. Whether their excess
really is debris diskemission, and what these debris disks can tell us
about how these stars formed and the status of planetary formation
within them, is the subject of my research.
The research can be broken down into four main areas:
- Identification - The first area concerns identifying
which main sequence stars may have debris disks. This involves comparing surveys
of IR sources (such as IRAS and MSX) to catalogs of main sequence stars
(e.g., the Michigan Spectral Catalog). The issues associated with this area
include how to determine the stellar properties, in particular how to determine
the contribution of the stellar photosphere to the IR flux, how to
distinguish between different types of IR excess emission (e.g., free-free emission
and debris disk dust emission), as well as contending with the other
observational uncertainties such as position and flux errors and IR contamination by
cirrus.
- Debris disk database - We have compiled a web-based
database of information (from SIMBAD, VIZIER, published and unpublished
observations, plus some modelling analysis) on the 300 or so debris disk candidates
that were identified in surveys of the IRAS databases. This is accessible
here.
- Observation - A debris disk system is so complicated
that there are many observations that need to be done before we can even begin to
understand it. As well as general information about the stellar system
(such as age, spectral type, are there any binary companions, etc, all
of which may require a further set of observations), here follows a
list of some of the types of observations that we are doing:
- Broad band photometry - The spectral energy
distribution of the thermal emission is important since it allows us to determine the
temperature of the dust, which in turn gives its distance from the star. Using IRAS
mid-IR and far-IR fluxes it was shown that the dust emission from most
Vega-type stars is cool (50-100 K) implying that the dust is in regions
analagous to the Kuiper belt of comets in the solar system (>30 AU
from the star). We have carried out sub-mm (450 and 850um) photometry using
SCUBA at the JCMT to extend the SEDs to longer wavelengths. The benefit
of these observations is that the slope of the SED at these wavelengths
is indicative of the largest grains in the disk.
- Imaging - Ideally we would like a direct measurement
of the spatial distribution of the dust around the star. The problem is that we are
limited by the resolution and sensitivity of currently available astronomical
instruments which mean that only the closest and brightest disks are resolvable. So
far 4 disks have been resolved in the sub-mm using SCUBA (Vega, beta
Pictoris, Fomalhaut, and epsilon Eridani), and a further two have been imaged in
the mid-IR using OSCIR (HR 4796 and HD 141569; these have also been
imaged in the near-IR using NICMOS on the HST). We have observing programs in
place to image debris disks using both of these instruments.
- Spectroscopy - There are several spectral features
that have been shown to be indicative of the composition of the debris dust (e.g., the
9.7um silicate feature). Observations of these features can be modelled
to obtain information on the size, composition and spatial extent of
the dust. We aim to obtain such observations using OSCIR, MICHELLE, and
SIRTF.
- Spectral line - It is of great importance to determine
whether these stars still have gas around them, since the gas is indicative of the
evolutionary status of the disk system. We have carried out a search for CO J=3-2
line emission from a sample of bright debris disks from the JCMT.
- Zodiacal cloud - While we have only been talking about
exozodiacal clouds until now, the same arguments apply for the zodiacal cloud.
However, since it is closer, and hence ubiquitous, we have to use different techniques.
Most information on the zodiacal cloud thermal emission comes from space-based
satellites such as IRAS, COBE, ISO, MSX, SIRTF. However, there is much
more information available about the zodiacal cloud system, since we
can measure the sources of dust (the asteroids and comets) as well as
measuring the properties of the dust itself.
- Modelling - The interpretation of debris disk
observations is based on the method of comparing those observations with pretend observations
of a model of the disk. This model will have various free parameters
that will be constrained by the observations. The more observational
information that is available, the more complicated the model. This means that a
model of the zodiacal cloud can have far more free parameters than a debris
disk for which we may only have broad band photometry. The input for one of
my model observations depends on the theory being tested, but in
general consists of:
- Spatial distribution - A model of the
three-dimensional distribution of material in the disk. This can range in complexity from a simple
parametric model with free parameters of the inner and outer cutoffs with a power
law distribution in between, to a full dynamical model that can
simulate dust clumps and asymmetries.
- Dust grain composition and morphology - The model for
debris disk dust grain optical properties that I have been using is based on that
developed by Li & Greenberg (1997). The grains are assumed to be made of a
silicate core (either amorphous or crystalline) with an organic refractory
mantle. They are assumed to be porous with a fraction of ice filling in the
gaps. The optical constants for these grains are added together assuming
various ratios for the components using Maxwell-Garnett effective medium theory.
- Dust size distribution - At the most basic level, we
would assume the particles in the disk to be all of the same size. However, more
realistically we would assume the size distribution to follow some distribution that
is based on a physical model for the collisional and dynamical
processes in the disk. Further adding to the complication, particles of different
sizes may have either different spatial distributions or different
compositions or morphologies.
- Stellar parameters - Combining the stellar spectrum,
the star's luminosity and mass, we can calculate the temperature, radiation forces
and emission efficiencies of the dust grains.
- Orientation - A map of the disk emission can be made
by defining the orientation of the disk to our line of sight and integrating the
emission from all dust grains along the line of sight of each pixel in the image.
- Physics - For any interpretation of the observation, we
need a model that is based on an understanding of the physical processes affecting
the disk's evolution so that the observations can be directly related to
that physics. In the case of the zodiacal cloud, that physics is relatively
well defined, whereas in debris disk systems we are much more unsure
about what we are looking at. In this instance we have to consider how all
possible physical processes that may be both currently and in the recent past
affecting the disks. The issues that I am studying at the moment are:
- Planets - How do the gravitational perturbations of
planets to the orbits of the debris material affect the structure of a debris disk?
Can we use observations of asymmetrical or clumpy debris disk structures to
infer the existence of unseen planets that may be hiding in the disk?
Observations of the zodiacal cloud show that planetary perturbations do cause
observable asymmetries in the structure of the zodiacal cloud. We also showed that
secular planetary perturbations could be causing the asymmetry observed
in the structure of the HR 4796 disk. Also, resonant planetary
perturbations may cause clumps in the structure of a debris disk that follow the
planet around its orbit.
- Collisions - The short collisional lifetimes of dust
particles in the debris disks means that they cannot be primordial, rather they must
have been created by collisions between larger bodies, which may
themselves have been created by collisions between even larger bodies. Such a
collisional cascade is how the dust in the zodiacal cloud is produced, by the
grinding down of the asteroid belt. However, collisional processes are not
completely understood even in the solar system; e.g., while the LDEF (Long
Duration Exposure Facility) result that most of the cross-sectional area of dust
being accreted onto the Earth is in grains between 100-200 micron in
size is understood in terms of the interplay between Poynting-Robertson drag
and collisions, this result has not been used to obtain quantitative
information about the collisional evolution of the zodiacal cloud. In terms of
debris disks, one important question that remains to be answered is whether
stochastic collisions between the largest members of the disk could cause clumps
(such as those observed in the disk around Epsilon Eridani) to form, and
whether this is statistically likely.
- Stellar Wind and Lorentz Forces - These are forces that are normally
ignored when modelling debris disks. In the case of the zodiacal cloud
it is certainly true that they can be ignored: stellar wind forces (which
act like Poynting-Robertson drag to make the particles spiral into the
star) are 1/3 as strong as those from radiation forces, Lorentz forces
are also substantially lower than other perturbing forces (except maybe
in the outer solar system). However, this rationale may not be applicable
to dust around other main sequence stars where these forces may even dominate
the dust's evolution; but we do not generally know the structure and magnitude
of a star's wind, nor do we know the structure of its magnetic field.
- Binary Companions and Stellar Flybys - Gravitational perturbations
from a binary companion, or from a stellar flyby, may act to perturb the
disk in a similar way to perturbations from a planetary sytem resulting
in distinctive features in the structure of the disk. Of the six resolved
debris disks, three are in wide binary systems (Fomalhaut, HR 4796, HD
141569), and another exhibits structure that can be explained in terms
of a recent stellar flyby (beta Pictoris). Is this coincidence? Or is the
existence of a disk linked to the binarity of the system, maybe because
the passing of a companion stirs up the normally quiescent disk, causing
more violent collisions and a corrsepondingly brighter disk? Certainly
if a disk is in a binary system, the binary orbit must be determined if
we are to understand its effect on the evolution of the disk; this is
not always easy in the case of wide binary orbits!
