Omega Capricorni, which is
runaway star.[7]
In
Chinese name for ω Capricorni itself is 天田二 (Tiān Tián èr, English: the First Star of Celestial Farmland.)[13]
This is an
luminosity of the Sun from its bloated photosphere at an effective temperature of 3,915 K.[1] It is a barium star,[6] showing an overabundance of the s-process elements. This suggests that Omega Capricorni has an orbiting white dwarf companion.[14]
