Abstract

I present a discovery of hierarchical triple system J060242.22+332452.7. Inner contact binary system shows clear eclipse timing variation (ETV) due to light time travel effect (LTTE), with LAMOST medium resolution spectra reveals radial velocity (RV) changes of the third star. Joint fit of ETV and RV allows determination of outer orbit with period Pout=1866±6 days and e3=0.40±0.05. The masses are MAB, Csin3i3=2.02±0.22, 0.86±0.08 M⊙. This system is expected to have an astrometric orbit in the next data release of Gaia.
