Gamma Comae Berenices

This is an evolved K-type giant star with a stellar classification of K1 III Fe0.5. The suffix notation indicates the star displays an overabundance of iron in its spectrum. It is most likely (91% chance) on the horizontal branch with an age of 2.7 billion years. If this is true, then it has an estimated 1.65 times the mass of the Sun and has expanded to nearly 12 times the Sun's radius. The star is radiating 58 times the Sun's luminosity from its enlarged photosphere at an effective temperature of around 4,652 K. Gamma Comae Berenices appears as part of the Coma Star Cluster, although it is probably not actually a member of this cluster.
