VV Vir BVRI differential photometry

Listed in IVOA Registry (Virtual Observatory)

VV Vir is a near-contact but detached mid-G-type eclipsing binary with an asymmetrical light curve due to a weak but regular mass exchange.

Description

The binary is apparently approaching contact and has a stream impact spot on the secondary component that is responsible for a quadratically [dP/P=(-7.8+/-0.2)x10^-11^] decreasing period. Our period study included more than 140 minima observed over the past 60 years.

We explore other possible near-contact configurations for this binary.
