HD 59640
HD 59640 is a solitary white hued star located in the southern circumpolar constellation Volans. It has an apparent magnitude of 6.48, placing it near the limit for naked eye visibility. Gaia DR3 parallax measurements place the object at a distance of 262 light years and it is receding with a heliocentric radial velocity of . At its current distance, HD 59640's brightness is diminished by three tenths of a magnitude due to interstellar dust. This is an ordinary A-type main-sequence star with a stellar classification of A3 V. It has 1.82 times the mass of the Sun and 1.77 times its radius. It radiates 13.7 times the luminosity of the Sun from its photosphere at an effective temperature of . HD 59640 has an iron abundance 63% that of the Sun, making it metal deficient. In 2020, Maximillian N. Günther and colleagues found the object to be an eruptive variable star with flares lasting up to 10 minutes. However, they are rather small, with the maximum being only two hundredths of a magnitude. References
