The two system components A and B are both A-type main sequence stars; which means they are hotter, larger, and more luminous than the Sun. The primary is spinning rapidly and the secondary more slowly. The primary has 2.46 times the mass of the Sun and 2.26 times the Sun's radius. It is radiating 39.8 times the Sun's net luminosity from its photosphere at an effective temperature of. The secondary 2.23 times the mass and 1.74 times the first of the Run. It shines with 16.9 times the luminosity of the Sun at.
