Eccentric Oddities: Surprise Discovery of Mysterious Mini-Neptune Exoplanets

Researchers discovered four mini-Neptunes with volatile-rich compositions around red dwarfs, using both space and ground-based telescopes.

Researchers discovered mini-Neptunes[1] around four red dwarfs[2], which are named TOI-782, TOI-1448, TOI-2120, and TOI-2406, using observations from a global network of ground-based telescopes with MuSCATs and the TESS space telescope.[3]
These four mini-Neptunes are close to their parent stars, and the three of them are likely to be in eccentric orbits (TOI-782 b, TOI-2120 b, TOI-2406 b).
These mini-Neptunes are not rocky planets like Earth but may be Neptune-like planets.
