Delta1 Canis Minoris
Delta1 Canis Minoris is a solitary, yellow-white hued star in the constellation Canis Minor. Its name is a Bayer designation that is Latinized from δ1 Canis Minoris, and abbreviated Delta1 CMi or δ1 CMi. This star is faintly visible to the naked eye with an apparent visual magnitude of +5.25. Based upon an annual parallax shift of as seen from Earth, this star is located roughly 820 light years from the Sun. It is drifting further away with a line of sight velocity of +29 km/s.
Houk and Swift list a stellar classification of F0 V for Delta1 Canis Minoris, indicating it is an F-type main-sequence star. However, Cowley et al. gave it a class of F0 III, which would suggest it is instead an evolved giant star. The spectrum displays a higher than solar metallicity – a term indicating the abundance of elements other than hydrogen and helium compared to the Sun. The star is spinning with a projected rotational velocity of 50 km/s. Based on stellar models, it has 4.3 times the mass of the Sun and 11.6 times the Sun's radius. It is radiating 542 times the Sun's luminosity from its photosphere at an effective temperature of 7,210 K.
