| Abstract | Context. V617 Sgr is a V Sagittae star - a group of binaries thought to be the galactic counterparts of the Compact Binary Supersoft X-ray Sources - CBSS. Aims. To check this hypothesis, we measured the time derivative of its orbital period. Methods. Observed timings of eclipse minima spanning over: 30 000 orbital cycles are presented. Results. We found that the orbital period evolves quite rapidly: P/P = 1.1 x 10(6) years. This is consistent with the idea that V617 Sgr is a wind driven accretion supersoft Source. As the binary system evolves with a time-scale of about one million years, which is extremely short for a low mass evolved binary, it is likely that the system will soon end either by having its secondary completely evaporated or by the primary exploding as a supernova of type Ia. |
