HD 24141
From Wikipedia, the free encyclopedia
HD 24141, also known as HR 1192, is a star located in the northern constellation Camelopardalis, the giraffe. It is faintly visible to the naked eye as a white-hued point of light with an apparent magnitude of 5.79.[3] The object is located relatively close at a distance of 176 light-years based on Gaia DR3 parallax measurements[2] and it is slowly drifting closer with a heliocentric radial velocity of −0.2 km/s.[7] At its current distance, HD 24141's brightness is diminished by 0.17 magnitudes due to interstellar extinction[16] and it has an absolute magnitude of +2.28.[1]
It is not entirely certain whether HD 24141 is an Am star or not.[17] One stellar classification is kA3hF0mF0,[4] which indicates that it is an Am star with the calcium K-lines of an A3 star and the hydrogen and metallic lines of a F0 star. However, Abt & Levy (1985) gave a class of A7 V,[5] indicating that it is instead an ordinary A-type main-sequence star. HD 24141 has 1.92 times the mass of the Sun and it is estimated to be only 15 million years old.[10] It radiates 10.66 times the luminosity of the Sun[2] from its photosphere at an effective temperature of 8,518 K.[10] These parameters correspond to a radius that is 72% larger than the Sun's.[11] HD 24141 has a near-solar metallicity at [Fe/H] = −0.02[13] and it spins modestly with a projected rotational velocity of 53 km/s.[14]
Most sources generally agree that HD 24141 is a solitary star.[18][5][19] A 2014 multiplicity survey found a 7th magnitude companion with a mass of 0.77 M☉[8] located 1.02" away from the star[8] along a position angle of 69°. Another 15th magnitude companion designated as C is located 1216″ away along a position angle of 187°.[20] The object appears to share the same proper motion as HD 24141,[9] but the Gaia DR3 parallax is different and it is considered very unlikely that the two are physically associated.[21]
