Star in the constellation Lyra
HD 171301 is a suspected binary star [ 11] system in the northern constellation of Lyra . It has not been well-studied.[ 5] The brighter member of the pair, designated component A,[ 3] has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of 5.47.[ 2] The system is located at a distance of approximately 347 light years from the Sun based on parallax , but is drifting closer with a radial velocity of −10 km/s.[ 6]
The stellar classification of HD 171301 is B8IV,[ 4] matching a late B-type star that may be a subgiant that is evolving off the main sequence . HD 171301 appears to be a type of chemically peculiar mercury-manganese star .[ 5] It has an estimated mass three[ 7] times that of the Sun and 2.7 times the Sun's radius.[ 8] The star is spinning with a projected rotational velocity of 36 km/s.[ 5] It is radiating 124[ 7] times the luminosity of the Sun from its photosphere at an effective temperature of 11,695 K.[ 7]
Its companion, component B, is a 13th magnitude star of an unknown spectral type.[ 12] It was first reported by S. W. Burnham in 1891. As of 1998, it was located at an angular separation of 6.7 arcseconds from the brighter star along a position angle of 157°.[ 3]
