HD 52265 is a star with an orbiting exoplanet companion in the equatorial constellation of Monoceros. It is dimly visible to the naked eye with an apparent visual magnitude of 6.29.[1] The star is located at a distance of 98 light-years based on parallax measurements, and is drifting further away with a heliocentric radial velocity of 54 km/s.[1] It has been given the proper name Citalá, after "river of stars" in the native Nahuat language. The name was selected in the NameExoWorlds campaign by El Salvador, during the 100th anniversary of the IAU.[8][9]

This is a G-type main-sequence star with a stellar classification of G0 V.[3] It is 21% more massive than the Sun and is 27% larger in radius. The star is 2.6 billion years,[5] and is spinning with a rotation period of 12.3 days.[6] It is radiating more than double the luminosity of the Sun from its photosphere at an effective temperature of 6,163 K.[5] The level of chromospheric activity is similar to the Sun.[4]

Planetary system

In 2000 the California and Carnegie Planet Search team announced the discovery of an extrasolar planet orbiting the star.[4] It was independently discovered by the Geneva Extrasolar Planet Search team.[10][11] The second planet in the system is suspected since 2013.[12] The planet has since been designated Cayahuanca by the IAU, which means "the rock" in the Nahuat language.[9]
