HD 36187

HD 36187, also known as HR 1835, is a solitary, bluish-white hued star located in the southern constellation Columba, the dove. It has an apparent magnitude of 5.55, making it faintly visible to the naked eye under ideal conditions. Based on parallax measurements from the Gaia spacecraft, it is estimated to be 282 light years away from the Solar System. However, it is receding rapidly with a heliocentric radial velocity of. At its current distance, HD 36187's brightness is diminished by 0.21 magnitude due to interstellar dust.
HD 36187 has a stellar classification of either A1 V or A0 V, depending on the source. Nevertheless, both classes indicate that it is an ordinary A-type main-sequence star that is fusing hydrogen in its core. It has double the mass and radius of the Sun. It radiates 48 times the luminosity of the Sun from its photosphere at an effective temperature of. HD 36187 is estimated to be 311 million years old, having completed 66.9% of its main sequence lifetime. Like many hot stars HR 1835 spins rapidly, having a projected rotational velocity of.
