Abstract:
The nearby young star beta Pictoris hosts a rich and complex planetary
system, with at least two giant planets and a nearly edge-on debris
disk that contains several dynamical subpopulations of planetesimals.
While the inner ranges of the debris disk have been studied
extensively, less information is known about the outer, fainter parts
of the disk. Here we present an analysis of archival FORS V-band
imaging data from 2003-2004, which have previously not been explored
scientifically because the halo substructure of the bright stellar
point spread function is complex. Here we present the deepest imaging
yet for the outer range of the beta Pic disk.
