HD 52265 b, formally named Cayahuanca, is a
California and Carnegie Planet Search team and the Geneva Extrasolar Planet Search team independently of each other.[1][2][3] By studying the fluctuations of the brightness of a host star, the inclination of the stars equator was determined. This allowed to calculate its true mass, assuming that the planet orbits in the plane of the star's equator.[6]
Naming
The planet HD 52265 b is named Cayahuanca. The name was selected in the NameExoWorlds campaign by El Salvador, during the 100th anniversary of the IAU. Cayahuanca means "The rock looking at the stars" in the native Nahuat language.[7][8]
