Hst, Re J1255+266, Cataclysmic Variable
Scientific paper
Dr. Paula Szkody (University of Washington) and collaborators have requested our help in monitoring the cataclysmic variable RE J1255+266 for Hubble Space Telescope observations. RE J1255+266 has not previously been 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. This object is very faint at quiescence, with V<19.0. 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, and will also be used in the analysis of the resulting data. Observers should monitor this object nightly beginning now through at least May 15 UT; the science observing window closes at 09:30 UT on 2008 May 14 UT. In the event of an outburst, please contact the AAVSO immediately. CCD observers are asked to use filters if possible, preferably V, but B, Rc, and Ic may also be used. Please use sufficient exposure (with S/N = 10) to reach at least the 16.998V comparison star. Please submit data to the AAVSO International Database using the name RE J1255+266 or the AUID 000-BCY-206.
