Cor Caroli (α CVn / α Canum Venaticorum / Alpha Canum Venaticorum) is the brightest Star in the northern Constellation Canes Venatici . The name ''Cor Caroli'' means ''Charles' heart'', and was named most likely by Edmond Halley in honour of either Charles I , who was executed or Charles II Of England , his son, who was restored to the throne after the Interregnum following his father's death. Cor Caroli is a Binary Star which has a combined Apparent Magnitude of +2.89. The two stars are 19.6 Arcsecond s apart on the sky and are easily resolved in small telescopes. It is approximately 110 Light Year s from Earth . The main star, α&2 Canum Venaticorum, is the prototype of a class of Variable Star s, the so-called α&2 Canum Venaticorum Star s. These stars have a strong Magnetic Field , which is believed to produce starspots of enormous extent. Due to these starspots the brightness of α&2 Canum Venaticorum stars varies considerably during their rotation. The brightness of α&2 Canum Venaticorum varies between +2.84 Magnitude and +2.94 with a period of 5.47 days. Its Spectral Type is A0. The companion, α¹ Canum Venaticorum, of spectral type F0, is considerably fainter at +5.5 magnitude. Cor Caroli marks the northern vertex of the Diamond Of Virgo Asterism . |
