34 Leonis Minoris

34 Leonis Minoris (34 LMi), also known as HD 91365 or 11 H. Leonis Minoris is a solitary star located in the northern constellation Leo Minor. It is faintly visible to the naked eye as a white-hued point of light with an apparent magnitude of 5.58. Gaia DR3 parallax measurements imply a distance of 510 light-years, and it is currently receding with a poorly constrained heliocentric radial velocity of $$. At its current distance, 34 LMi's brightness is diminished by interstellar extinction of 0.16 magnitudes and it has an absolute magnitude of −1.02.

The object has received several stellar classifications over the years. Most sources generally agree that it is an early A-type main-sequence star with the classes ranging from A0 to A2. Anne Cowley and colleagues found that 34 LMi has broad or nebulous absorption lines in its spectrum, which could be a result of rapid rotation. However, D. R. Palmer gave a class of A0 IV, indicating that it is an evolved A-type subgiant. Richard O. Gray and Robert F. Garrison found a class of A1 III-IV, indicating that it has a luminosity class intermediate between a subgiant and giant star.

34 LMi has 2.4 times the mass of the Sun and an enlarged radius of. It radiates 323 times the luminosity of the Sun from its photosphere at an effective temperature of $$. At the age of 406 million years 34 LMi is 1.9% past its main sequence lifetime, meaning that it has evolved to the subgiant branch. The star has a near-solar metallicity at [Fe/H] = −0.03 (93% solar). Like many hot stars 34 LMi spins rapidly, having a projected rotational velocity of $$.
