UBV Photometry of Er-Vulpeculae
Abstract
UBV photometry of RS CVn-type eclipsing binary system ER Vulpeculae has been presented. The period comes out to be 0{./d}698093. The average depths of primary and secondary minima are, respectively, 0{./ m }21 and 0{./ m }12. The colours at various phases have been given. A dip is seen around phase 0{./ p }73 as was seen in the observations of Arevaloet al. (1988). Large scatter is present in the observations as noticed earlier, and may be due to activity of the components.
