Webb24 okt. 2024 · There are several aspects to TOI-3757 b that are mysterious, including how a gas giant star can form in orbit around a red dwarf star. The researchers believe that the rocky core of the gas giant formed more slowly than other similar exoplanets, leading to a more gradual accumulation of the gas under the influence of the gravity of the protoplanet.
