HD 25291

HD 25291, also known as HR 1242, is a solitary, yellowish-white hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.12, making it one of the brighter members of this generally faint constellation. The object is relatively far at a distant of approximately 2,100 light years but is drifting closer with a heliocentric radial velocity of $$.

HD 25291 has a general stellar classification of F0 II, which indicates that it is an evolved early F-type bright giant. It has also been given a class of F2 Ia, instead suggesting a slightly cooler and more luminous supergiant. Nevertheless, it has 8.8 times the mass of the Sun but at an age of 32 million years, it has expanded to 50.1 times its girth. It radiates at a bolometric luminosity 9,878 times greather that of the Sun from its enlarged photosphere at an effective temperature of $$. HD 25291 is slightly metal deficient, with an iron abundance 85% of solar levels. It spins modestly with a projected rotational velocity of $$.

Tetzlaff et al. (2011) found the object to be a runaway star with a peculiar velocity of $-20.3 km/s$, which is high compared to neighboring stars.
