Abstract:
I present BVRI photometry of short-period (P<1d) eclipsing RS CVn
binary star systems collected between 1988 and 2009 at Mount Laguna
Observatory. Most of the data are for ER Vul and WY Cnc, with light
curves nearly every year during that time period. I also present light
curves for at least several years for XY UMa, BH Vir, CG Cyg, RT And,
and UV Psc. I have fewer light curves for SV Cam, UV Leo, 1E1919+0427,
and GSC 2038-0293. In addition to the eclipsing short-period systems,
I also include UBVRI data for two longer period non-eclipsing RS CVn
binary systems: UZ Lib and DM UMa, as well as two active chromosphere
single stars: FK Com and HD 199178.
Description:
I used the 0.6-m (24") telescope at Mount Laguna Observatory operated
by San Diego State University for all the observations reported in
this paper.
