V373 Cas is a spectroscopic binary in the constellation Cassiopeia. It is composed of two hot blue-white giant stars that have exhausted their core hydrogen and expanded off the main sequence. Lyubimkov and colleagues analysed spectral and radial velocity to calculate that the stars were 18.6 ± 2.4 and 14.2 ± 1.9 times as massive as the Sun and the age of the system at around 7-8 million years old. ==References==
