J/PASJ/59/955       UBVRI differential photometry of BH Vir  (Xiang+, 2007)

Evidence of hot spot activity on BH Virginis. Xiang F., Tao X., Tian Y. <Publ. Astron. Soc. Jap., 59, 955-960 (2007)> =2007PASJ...59..955X
ADC_Keywords: Binaries, eclipsing ; Photometry, UBVRI Keywords: stars: activity - stars: eclipsing binaries - stars: individual (BH Vir) - stars: star-spots Abstract: Photoelectric light curves of BH Vir in the UBVRI bands observed by Arevalo et al. (1987IBVS.3117....1A, 1990ApJ...354..352Z) in 1986 were analyzed by using the latest version of the Wilson-Devinney program and to investigate the photometric parameters and spot activity. Satisfactory fits were obtained by assuming a hot spot only on the secondary star.
