HAT-P-12b
Template:Short description Script error: No such module "infobox".Script error: No such module "Check for unknown parameters". HAT-P-12b, formally named Puli,[1] is an extrasolar planet approximately 468 light years away from Earth, orbiting the 13th magnitude K-type star HAT-P-12, which is located in Canes Venatici constellation. It is a transiting hot Jupiter that was discovered by the HATNet Project on April 29, 2009.
HAT-P-12b is a H/He-dominated gas giant planet with a core mass of 11.3Script error: No such module "Su". M🜨 and is moderately irradiated by its low-metallicity host star.[2] Therefore, HAT-P-12b is most likely an H/He-dominated planet with a core of perhaps ~10 M🜨, and a total metal fraction of ~15%. This makes HAT-P-12b the least massive H/He-dominated gas giant planet found to date; the previous record holder was Saturn.[3]
In 2020, the obtained transmission spectra have revealed that the atmosphere of HAT-P-12b is cloudy,[4] with haze above cloud tops. Water was detected.[5] The prevalence of clouds and hazes in planetary atmosphere was disputed in 2021 though.[6]
In August 2022, this planet and its host star were included among 20 systems to be named by the third NameExoWorlds project.[7] The approved names, proposed by a team from Hungary, were announced in June 2023. HAT-P-12b is named Puli and its host star is named Komondor, after the Hungarian Puli and Komondor dog breeds.[1]
