Scientific paper
We propose new methods to examine the circumstellar disk around Beta Pictoris in order to determine its radial profile, and hence (in combination with IRAS data) to fix its albedo and temperature profile. These observations will extend previous extensive ground based coronagraphic observations, and models by members of the science team. The data will enable us to understand better the central clearing in the disk and whether it is caused by sublimation or possible planet formation. They will also constrain the geometric propertie of the disk including its inclination angle, vertical thickness and radial profile. Such observations limit models for the dynamics of the disk, includin its velocity dispersion and hence mass distribution, and radial mass transport mechanisms. If density waves or clear zones are observed, they will give indirect evidence for the presence of massive bodies (planets) in the disk. Th observations involve a combination of roll deconvolution, polarizers and PSF modelling in order to allow the central stellar image and associated scattered light to be subtracted. Ultraviolet observations will constrain the particle size distribution and the composition of the disk. The observations require the new capabilities in WFPC2 provided by the absence of bleeding across columns, as well as its UV capabilities.
