 It has a stellar classification of B0.5 V, making it a B-type main sequence star that is generating energy at its core through the nuclear fusion of hydrogen.Component A is radiating over 28,000 times the Sun's luminosity from its outer envelope at an effective temperature of 26,500 K. This gives the star the blue-white hue that is typical of B-type stars.Epsilon Persei A is a Beta Cephei variable star with a primary pulsation period of 0.1603 days, or 6.24 cycles per day.
