Gamma Equulei

It is located at a distance of around 118 light-years (36 parsecs) from Earth and is visible to the naked eye with a slightly variable apparent visual magnitude of around 4.7.

[6] The primary component of γ Equulei is a chemically peculiar star with a stellar classification of A9VpSrCrEu.

[3] It has a spectrum corresponding to an A9 main sequence star, but with unusual abundances of strontium, chromium, and europium.

[12] γ Equulei has particularly sharp absorption lines in its spectrum, a sign of very slow rotation.

[13] The surface magnetic field of γ Equulei undergoes slow variation, ranging from +577 G to –1,101 G.[15] Although only 67 years of magnetic field measurements are available, a period of 97.16±3.15 years has been fit to the data.
