Further confirmations of mass transfer in Algol type binary U Sagittae
Abstract
This paper describes how a new photometric V light curve solution of Algol type binary U Sge was obtained using Wilson Devinney code. I also discuss how the physical and orbital parameters, along with absolute dimensions of the system, were determined. The Roche lobe configurations of the system indicate that the secondary component has filled its Roche lobe and therefore is losing mass at the rate of 6.15×10-7 M sun yr-1. The conservative mass flow is the most likely process in this system.
