Delta Piscis Austrini, Latinized from δ Piscis Austrini, is a yellow-hued star[1] in the southern constellation of Piscis Austrinus. It is visible to the naked eye with an apparent visual magnitude of +4.175.[2] There is a magnitude 9.86[1] common proper motion[1] companion located at an angular separation of 5.2 arc seconds – the pair most likely form a binary star system.[3] Based upon an annual parallax shift of 18.9796 mas as seen from the Gaia satellite, Delta Piscis Austrini is located 172 ± 2 light-years from the Sun.[4]
The primary, component A, is an evolved G-type giant star with a stellar classification of G8 III.[5] At the age of about 3.74 billion years[6] it is a red clump star, which indicates it is generating energy through helium fusion at its core.[7] The star has an estimated 1.42 times the mass of the Sun and it radiates 52 times the solar luminosity from its photosphere at an effective temperature of 4.828 K.[6]
Delta Piscis Austrini is moving through the Galaxy at a speed of 13.8 km/s relative to the Sun. Its projected Galactic orbit carries it between Шаблон:Convert and Шаблон:Convert from the center of the Galaxy.[8]
Chinese name
The Chinese name for Delta Piscis Austrini is Шаблон:Lang (Шаблон:Lang) meaning Materials for Making Tents, because this star is marking itself and stand alone in Materials for Making Tents asterism, Encampment mansion (see : Chinese constellation).[9] 天綱 (Tiān Gāng) westernized into Tien Kang, meaning "the Heavenly Rope" in R.H. Allen's work, but the name is for the asterism consisting this star, β PsA and ζ PsA.[10]
