39 Leonis
The stellar classification of 39 Leonis is F6 V, indicating it is a main sequence star. It shines with a luminosity more than double that of the Sun, although it has nearly the same mass and size. This is a mature star with an estimated age of 6.3 billion years. The abundance of elements other than hydrogen and helium is about half that in the Sun, making this a metal-poor star. The effective temperature of the stellar atmosphere is 6,118 K, giving it the yellow-white hued glow of an F-type star.
Observations made with the Akari satellite at a wavelength of 18 μm show an excess of infrared emission. This suggests the presence of an inner debris disk orbiting the star at a distance greater than four astronomical units (AU). There was no significant excess found at 22 μm.
A companion star is located at an angular separation of 7.72″ along a position angle of 302.7°—this corresponds to a projected separation of 175 AU. It is a red dwarf star with a classification of M1 and an apparent visual magnitude of 11.40.
