HAT-P-12b is a H/He-dominated gas giant planet with a core mass of 11.3+2.6 −2.1 M🜨 and is moderately irradiated by its low-metallicity host star.[3] 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 wasSaturn.[1]
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 thirdNameExoWorlds project.[7] The approved names, proposed by a team fromHungary, were announced in June 2023. HAT-P-12b is namedPuli and its host star is namedKomondor, after the HungarianPuli andKomondor dog breeds.[2]
