Abstract:
Complete Bessel BVRcIc light curves of V1043 Cassiopeia [2MASS
J00371195+5301324, Mis V1292, USNO-A2.0 1425-00875743,
α(2000)=00h37m11.95s, δ(2000)=+53°01'32.5"] are
analyzed. The system is a member of the small group of pre-contact W
UMa binaries (PCWBs). Its light curve has the appearance of an Algol
(EA) light curve, however it is made up of dwarf solar type components
in a detached mode with a period of only 0.6616days. The analysis
includes a period study, an improved ephemeris, a mass ratio search,
and a simultaneous BVRcIc Wilson-Devinney solution. We document
about 20 other PCWBs given in the literature. Several have RS CVn-like
properties.
Description:
Our BVRcIc observations were taken on 2010 September 28 and 29 at
Lowell Observatory with the 0.81m reflector on Anderson Mesa, outside
Flagstaff with National Undergraduate Research Observatory (NURO) time
and a CRYOTIGER cooled (< -100°C) 2K*2K CCD NASACAM. Exposure
times were 150s in B, 45s in V, 40s in Rc, and 40s in Ic.
