The primary component is an Ap star on the main sequence with a stellar classification of A2VpSrCrEu,[3] where the suffix notation indicates abnormal abundances of strontium, chromium, and europium in the stellar atmosphere. It is an Alpha2 Canum Venaticorum variable; its apparent magnitude varies from 4.70 down to 4.75 with a period of 12.5 days.[3] A rotationally-modulated magnetic field has been measured, varying from −72±9 G to 57±9 G. It has an estimated rotation period of 5.98±0.06 d, although this is in need of further confirmation.[10]
