HD 165590 is a quintuple system dominated by the binary Algol variable star known as V772 Herculis. The system lies in the constellation of Hercules about Шаблон:Val from the Sun, and is suspected to be a part of the Pleiades moving group.[1]

System

The primary star is an eclipsing binary ADS 11060A composed of G1 and K6 young main-sequence stars with strong starspot activity.[2] A radio flare from the star V772 Her was detected in 2011.[3] The period of the components of the primary, ADS 11060Aa and ADS 11060Ab, is 0.87950 days.[1]

A main-sequence companion star ADS 11060B of spectral type G5 at a separation of 0.491 arcseconds,[4] is orbiting the primary with a period of 20.08 years.[1]

Also, there is a suspected companion binary star ADS 11060C (Gaia EDR3 4576326312901650560)[5] at a projected separation of 29 arcseconds (1200 AU) from ADS 11060AB. ADS 11060C is composed of K7 and M0 main-sequence stars, orbiting each other with a period of 25.7631 days without eclipses. The binary is a BY Draconis variable[6] with the variable star designation V885 Herculis.

The planetary orbits in the habitable zones in the system ADS 11060AB are unstable due to the gravitational influence of the stellar companions.[7]
