HAT-P-12

HAT-P-12, also named Komondor, is a magnitude 13 low-metallicity K dwarf star approximately 463 light years away in the constellation Canes Venatici, which hosts one known exoplanet.

Nomenclature

The designation HAT-P-12 indicates that this was the 12th star found to have a planet by the HATNet Project.
In August 2022, this planetary system was included among 20 systems to be named by the third NameExoWorlds project. The approved names, proposed by a team from Hungary, were announced in June 2023. HAT-P-12 is named Komondor and its planet is named Puli, after the Hungarian Komondor and Puli dog breeds.

Planetary system

In 2009 an exoplanet, HAT-P-12b, was discovered by the HATNet Project orbiting this star. The planet was discovered using the transit method and confirmed by follow up radial velocity measurements. Transit-timing variations suggest the possible presence of additional non-transiting planets in the system.
