29 Persei

This is a B-type main-sequence star with a stellar classification of B3 V. During the 1930s it was reported to have a variable radial velocity, but that may instead have been due to instrument error. The star has a high rate of spin, showing a projected rotational velocity of 120 km/s. It has 6.8 times the mass of the Sun and about 3.9 times the Sun's radius. 29 Persei is radiating 960 times the Sun's luminosity from its photosphere at an effective temperature of 16,143 K.
