Am-звезда
In the past this star was suspected of being a Delta Scuti variable, which is rare for an Am star. This categorization was brought into question during observations in 1994 and it is most likely not inherently variable. The primary has double the Sun's mass and nearly twice its radius. It is rotating rapidly with a projected rotational velocity of 105 km s−1. (This rotation rate is synchronous with the orbital period.) Note that it is unusual for an Am star to have such a high rotational velocity. The outer envelope of the star is radiating energy at an effective temperature of 7,301 K, giving it the white-hued glow of an A-type star. The secondary component is a G-type or K-type star with around 90% of the mass of the Sun.
