Beta Coronae Australis

Beta CrA has a stellar classification of K0 II/III CN1.5, indicating that it is an evolved K-type star with the blended luminosity class of a bright giant and a regular giant star. The suffix CN1.5 indicates that the object has an anamolous overabundance of cyano radicals in its spectrum, making it a CN star. Having exhausted the supply of hydrogen at its core, the star has expanded to 39 times the Sun's girth. It has 5.17 times the mass of the Sun shines with a luminosity 614 times that of the Sun from its photosphere at a surface temperature of 4,575 K. Beta CrA is metal enriched (174% solar iron abundance) and spins modestly with a projected rotational velocity of 6.2 km/s.
