Otero, Sebastian Alberto
|
Quadriple system. AB is the 19. d. eclipsing binary. A is the SDOR outbursting object. C is a late O-type supergiant which is itself a binary in a highly eccentric (e = 0.82) 96.6 d. orbit. The EW: variability has P= 0.505054 d. Light curve is assymetric so it might not be eclipsing [VSX Team]. |
