Description


V505 Sgr is a classical Algol system consisting of an A2 V primary and a G5 IV secondary that fills its Roche lobe. New times of minimum light are presented. The period of the eclipsing system (1.18287d) varies, due in part to an orbital light-time effect. A third component has been detected that orbits the eclipsing pair. This investigation uses the SIMPLEX algorithm [Kallrath & Linnell, ApJ, 313, 346 (1987)] and the Differential Correction code [Wilson, ApJ, 234, 1054 (1979)] to analyze two separate datasets. The results indicate the third component, an F8 V star, contributes about 5% of the light to the system. The minimum projected distance between the third component and the eclipsing pair is 37 AU. This implies an orbital period of about 105 years, a value that differs with the O-C data. The photometric solution, combined with recent spectroscopic data, yields R(1)=2.14R(Sun) and R(2)=2.24R(Sun) and M(1)=2.20M(Sun) and M(2)=1.15M(Sun).
