Request to monitor SDSS074545 for HST Observations
Active Dates: Oct. 19, 2007 – Nov. 3, 2007
Abstract:
Dr. Paula Szkody (University of Washington) has requested our help in monitoring the cataclysmic variable SDSS074545 (SDSS J074531.92+453829.5) for upcoming Hubble Space Telescope observations. The HST observations are scheduled to be made during the week of 2007 October 29 -- November 03 UT. Monitoring this object during the two weeks prior to the observing window and intensive monitoring during the 24-48 hour period during which observations will be made is requested.
Justification:
SDSS074545 is a cataclysmic variable not previously seen in outburst, and is being observed as part of a larger study of pulsating white dwarf primaries in cataclysmic variables. In particular, Szkody and collaborators are investigating the effects that higher temperatures and larger rotation velocities caused by accretion have on the pulsation behavior. AAVSO observations are requested to ensure that the object is indeed faint when observed with HST, as it could damage the instrument if it were to go into outburst. AAVSO observations will be used to make a "go"/"no go" decision when the observing window opens, and will also be used in the analysis of the resulting data.
