HD 208741, also known as HR 8380, is a yellowish-white hued star located in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.91,[2] making it faintly visible to the naked eye. Parallax measurements place it at a distance of 211 light years,[1] and it is currently receding with a heliocentric radial velocityof8 km/s.[10]
HD 208741 has a 10th magnitude K-type main-sequence companion[9] separated by 34.8″.[4] Together, they make up a wide binary system designated collectively as CPD−76°1542.[4] Sir John Herschel, the discoverer of the pair, noted the primary to be a probable spectroscopic binary.[17]
This object has a stellar classification of F3 III,[6][7] indicating that it is a slightly evolved F-type star. Gaia Data Release 3 models it to be a dwarf that is 81.3% through its main sequence lifetime.[5] At present it has 1.52 times the mass of the Sun and a slightly enlarged radiusof2.6 R☉[12] due to its evolved state. It radiates at 12.9 times the luminosity of the Sun[13] from its photosphere at an effective temperatureof6,937 K.[14] HD 208741 has a metallicity twice the Sun's,[14] making it metal enriched. It is estimated to be 1.1 billion years old,[16] and is spinning with a projected rotational velocityof36 km/s.[15]
