Star in the constellation Taurus
HD 28375 is a single[ 10] star in theequatorial constellation ofTaurus , near the southern constellation border withEridanus . It was previously known by theFlamsteed designation 44 Eridani , although the name has fallen out of use because constellations were redrawn, placing the star out of Eridanus and into Taurus. The star is blue-white in hue and is dimly visible to the naked eye with anapparent visual magnitude of 5.53.[ 2] light-years based onparallax .[ 1] radial velocity of 18 km/s,[ 5] [ 2]
Cowley (1972) and later Bragança et al. (2012) found astellar classification of B3V[ 11] [ 12] B-type main-sequence star . Houk and Swift assigned it a class of B5 III/IV,[ 13] evolved star that is entering thegiant stage . It has five times themass of the Sun and is around three million years old,[ 6] projected rotational velocity of just 13 km/s.[ 8] [ 2] luminosity of the Sun from itsphotosphere at aneffective temperature of about 13,000 K.[ 3]
Aninfrared excess has been detected, indicating the presence of acircumstellar disk . The dust has a temperature of about 119 K and is orbitingAU star .[ 3]
