HD 41534 is a
binary star
[11] system in the southern
constellation of
Columba. It is dimply visible to the naked eye with a combined
apparent visual magnitude of 5.65.
[2] The distance to this system is approximately 950
light-years based on
parallax,
[1] and it is receding from the
Sun with a
radial velocity of +93 km/s.
[5] This is a
runaway star system with an unusually high
peculiar velocity of 187.6+12.2
−13.8 km/s.
[12] It is thought to have been ejected from the
OB association Sco OB 1 approximately 14 million years ago.
[13]
The primary component is a B-type main-sequence star with a stellar classification of B2V. [3] It displays microvariability with an amplitude of 0.0086 in magnitude and a frequency of 0.11316 cycles per day. [14] The star is an estimated 14 [6] million years old with a high rate of spin, showing a projected rotational velocity of 122. [8] It has seven [6] times the mass of the Sun and about four [7] times the Sun's radius. HD 41534 is radiating over 1,600 [2] times the luminosity of the Sun from its photosphere at an effective temperature of 20,000 K. [6]
