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. It is also a Beta Cephei variable star with a primary pulsation period of 0.1603 days, or 6.24 cycles per day. It may have multiple pulsation frequencies.
