Cataclysmic variables to be monitored for HST observations
Abstract:
Drs. Boris Gaensicke (Warwick University), Joseph Patterson (Columbia University, Center for Backyard Astrophysics), and Arne Henden (AAVSO), on behalf of a consortium of 16 astronomers, have requested the help of AAVSO observers in monitoring ~40 cataclysmic variables in support of Hubble Space Telescope observations to measure the temperatures, atmospheric compositions, rotation rates, and eventually masses of their white dwarfs.
Justification:
The primary purpose of the monitoring is to know whether each target is in quiescence immediately prior to the observation window; if it is in outburst it will be too bright for the HST instrumentation. Based on the information supplied by the AAVSO, the HST scheduling team will decide whether to go forward with the HST observations.
