16 Lyrae
16 Lyrae is a suspected astrometric binary star system in the constellation Lyra, located 126 light years away from the Sun based on parallax. It is visible to the naked eye as a dim, white-hued star with a combined apparent visual magnitude of 5.00. The system is moving further away from the Earth with a heliocentric radial velocity of +4.36 km/s. It is a suspected member of the Ursa Major Moving Group stream.
Cowley et al. (1969) found a stellar classification of A7 V for the visible component, matching an A-type main-sequence star that is generating energy through hydrogen fusion at its core. Abt and Morrell (1995) instead listed a class of A6 IV, suggesting it has left the main sequence and become a subgiant star.
16 Lyrae is 72% more massive than the Sun and irradiates 10.5 times the Sun's luminosity. It is 401 million years old with a high rate of spin, showing a projected rotational velocity of 85 km/s. The fast rotation make this star slightly oblate, with an equatorial radius of 1.644 R☉ and a polar radius of 1.622 R☉. Its effective temperature also vary across its surface due to rotation, from 8,200 K in the poles to 8,000 K in the equator.
This system is a source for X-ray emission with a luminosity of 105.3×1020 W, which is most likely coming from the unseen companion.
