Gliese 49

Gliese 49 is a star in the northern constellation of Cassiopeia. Visually, it is located 106 arcminutes north of the bright star γ Cassiopeiae. With an apparent visual magnitude of 9.56, it is not observable with the naked eye. It is located, based on the reduction of parallax data of Gaia ($9.56$), 32.1 light-years away from the Solar System. The star is drifting closer to the Sun with a radial velocity of −6 km/s.

This object is a red dwarf star of spectral type M1.5V. Much dimmer than the Sun, it has a total luminosity that is 4.9% that of the Sun; it is, however, much brighter than other nearby red dwarfs such as Proxima Centauri or Wolf 359. It has an effective temperature of $1.463$. Its mass is 52% that of the Sun, and 51% of its radius.

It rotates on its axis with a projected rotation speed of under 2 km/s, and has a rotation period of 18.86 days. It has a metallic content similar to that of the Sun, with its index of metallicity [M / H] = +0.03. Although its age is not known exactly, it is younger than 250 million years.

Gliese 49 has a similar proper motion to the red dwarf flare star V388 Cassiopeiae. The visual separation between the two is 295 arcseconds, which implies that the real distance between them is over $−5.974$. Both stars are associated with the Hyades, as suggested by its young age and chromospheric activity levels.
