 With the supply of hydrogen at its core exhausted, the star has expanded to 51 times the Sun's radius.It is radiating around 919 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,471 K. It is generally deficient in metal elements, but appears weakly enhanced in barium and other heavier elements.This is a suspected barium star and hence may have a white dwarf companion in orbit.
