19 Leonis Minoris
19 Leonis Minoris (19 LMi) is a spectroscopic binary located in the northern constellation Leo Minor. It has an apparent magnitude of 5.1, making it one of the brighter members of the constellation. The system is relatively close at a distance of 94 light years but is drifitng closer with a heliocentric radial velocity of . This spectroscopic binary can be classified as single lined because only the primary's spectrum can be observed clearly, with it having a stellar classification of F6 V. This makes it an ordinary F-type main-sequence star. The companion is probably a G-type main-sequence star of G0, having a mass 101% that of the Sun. The pair have a relatively circular orbit of about 9 days. 19 LMi has 129% the mass of the Sun and an effective temperature of , giving a yellow white hue. The object is somewhat evolved at an age of 2.5 billion years, having a slightly enlarged radius of  and a luminosity of , high for its class. 19 LMi has an iron abundance 123% that of the Sun, making it slighly metal enriched. It spins modestly with a projected rotational velocity of . References
