Spectroscopic observations of the interacting massive binary AQ Cassiopea

Ibanoglu, C.; Çakırlı, Ö.; Sipahi, E.

New spectroscopic observations of the double-lined eclipsing binary AQ Cas are presented. All available spectroscopic and photometric observations have been analysed for the fundamental properties of the components. Analyses show that the system consists of a massive primary with a mass of 17.63 ± 0.91 M_⊙ and radius of 13.48 ± 0.64 R
