| Abstract: | Photometric data of the new discovered binary GSC3658-0076 observed by González-Rojas et al.: 2003, IBVS, No. 5437.] were
analyzed using the latest Wilson-Devinney code. The system turns out to be a detached binary system with the primary component
almost filling its Roche lobe, while the secondary one is detached from the critical Roche lobe. According to the mass-radius
relation of unevolved (ZAMS) detached binaries given by Demircan and Kahraman: 1991, Ap&SS 181, 313.], the primary component is more evolved. These properties reveal that GSC3658-0076 may be at the beginning of the mass
transfer phase and may evolve from the present detached system into a contact binary or be in the broken-contact phase predicted
by TRO theory. |
