HD 84607
F-type subgiant; Sextans
HD 84607 (HR 3879; 1 G. Sextantis) is a solitary star[15] located in the equatorial constellation Sextans. It is faintly visible to the naked eye as a yellowish-white hued point of light with an apparent magnitude of 5.64.[2] The object is located relatively close at a distance of 250 light-years based on Gaia DR3 parallax measurements,[1] but it is receding with a heliocentric radial velocity of 7.8 km/s.[5] At its current distance, HD 84607's brightness is diminished by an interstellar extinction of 0.18 magnitudes[16] and it has an absolute magnitude +1.12.[6]
HD 84607 has a stellar classification of F0/2 IV,[3] indicating that it is a slightly evolved star with the characteristics of a F0 and F2 subgiant. At the age of 1.06 billion years,[7] the star is ceasing hydrogen fusion at its core and is cooling and expanding onto the red giant branch. It has 2.01 times the mass of the Sun[7] and a slightly enlarged radius 3.43 times that of the Sun.[8] It radiates 26.29 times the luminosity of the Sun[1] from its photosphere at an effective temperature of 6,919 K.[10] HD 84607 is metal enriched with an iron abundance of [Fe/H] = +0.14 or 138% of the Sun's[11] and it spins fairly quickly with a projected rotational velocity of 93.1 km/s within 1.51 days.[12]
