V Cephei

V Cephei is a white main sequence star in the constellation Cepheus. It only varies slightly by 0.03 of a magnitude. It was suspected of being variable by American astronomer Seth Carlo Chandler noting in 1890 that it varied by 0.7 magnitude but that it needed more confirmation. Subsequent observers were divided in whether they noted variability or not. A subsequent study with photoelectric photometry showed no variability.

With a spectral class of A1V, V Cephei is a main sequence star with a surface temperature of $9,004 K$. It has twice the mass of the Sun and, with nearly twice its radius, it shines at.
