This star has more than three times the mass of the Sun and is about 330 million years old.[6] The
spectrum of this star matches a
stellar classification of G8 II-III,[3] with the
luminosity class notation 'II-III' indicating it shows some traits of both a
giant star and a
bright giant. At this
evolutionary stage, the atmosphere has expanded to almost thirteen times the radius of the Sun and the outer envelope has an
effective temperature of 5,196 K.[6] X-ray emission has been detected from this star, with an estimated luminosity of 3 × 1029 erg s−1.[12]
In
Chinese, caused by adaptation of the European southern hemisphere constellations into the Chinese system, 夾白 (Jiá Bái), means White Patches Attached, and it refers to an asterism consisting of α Reticuli and
θ Doradus. Consequently, α Reticuli itself is known as 夾白二 (Jiá Bái èr, English: the Second Star of White Patches Attached.)[13]
