of . Component Ab is only slightly smaller, with 2.4 times the Sun's mass and radius, with a luminosity of 47 times the Sun and an effective temperature of 9,370 K.

Both stars are rotating rapidly and are significantly oblate, with equatorial radii larger than their polar radii. Gravity darkening results in their effective temperatures at the pole being higher than that of the equator. For component Aa, the polar radius and temperature are and 10,100 K,
