A Search for Circumstellar Disks and Planetary-Mass Companions around Brown Dwarfs in Taurus

A Search for Circumstellar Disks and Planetary-Mass Companions around Brown Dwarfs in Taurus During a 1-orbit program in Cycle 14, we used WFPC2 to obtain the first direct image of a circumstellar disk around a brown dwarf. These data have provided fundamental new constraints on the formation process of brown dwarfs and the properties of their disks. To search for additional direct detections of disks around brown dwarfs and to search for planetary-mass companions to these objects, we propose a WFPC2 survey of 32 brown dwarfs in the Taurus star-forming region.

We will obtain WFPC2 images of 32 brown dwarfs in the Taurus star-forming region through the F791W and F850LP filters. These filters were selected because they provide the optimum combination of 1) high spatial resolution for resolving companions and circumstellar emission (at the shorter wavelength), 2) sensitivity to cool, red companions (at the longer wavelength), and 3) colors that discriminate cool companions from field stars. Each target will be centered in the PC and observed in a two-point dither pattern (WFPC2-LINE). We have selected 3 different sets of exposure times and gains for 3 ranges of magnitudes of our targets to optimize sensitivity while avoiding saturation. For targets with I>17, we will obtain one CR-SPLIT 520 sec exposure in F791W and one CR-SPLIT 320 sec exposure in F850LP at each dither position with GAIN=7. For targets with I=16.3-17, we will use the same exposure times, but with GAIN=15 to prevent saturation. For targets with I<16.3, we will obtain one CR-SPLIT 400 sec exposure in F791W, one CR-SPLIT 320 sec exposure in F850LP, and one 40 sec exposure (no CR-SPLIT) in F791W at each dither position with GAIN=15. The 40 sec exposures will provide unsaturated data for the core of the PSF of the target. The long exposures will provide SN=3 for m791=25.5 and m850=24.5, which corresponds to companions with masses of 3 MJup at the distance and age of the targets. Each target will be observed in one orbit and one visit. There are no scheduling constraints for this program.
