Epsilon Phoenicis Explained

Epsilon Phoenicis is a star in the southern constellation of Phoenix. It is visible to the naked eye with an apparent visual magnitude of 3.87. The distance to this star is approximately 144 light years based on parallax measurements, but it is drifting closer with a heliocentric radial velocity of −9.2 km/s.

This is an evolved giant star with a stellar classification of K0III, a star that has used up its core hydrogen and has expanded. It is a red clump star, indicating that it has undergone helium flash and is currently on the core helium-fusing horizontal branch. Epsilon Phoenicis is radiating 67 times the luminosity of the Sun from its photosphere at an effective temperature of 4,862 K. Based on the elemental abundance of iron in the stellar atmosphere, the metallicity of Epsilon Phoenicis is similar to that of the Sun.
