This object is an
Ap star[15] with a
stellar classification of B9.5IIIspSi[5] matching a
lateB-typegiant star. The 'Si' suffix indicates an abundance anomaly of silicon. It is an
Alpha2 Canum Venaticorum variable that ranges from magnitude 4.68 down to 4.73 with a period of 1.89 days – the same as its rotational period.[6][12] It is 3.65 times as massive and 245 times as luminous as the Sun,[10] with 3.44 times the Sun's diameter.[11]
