At just 700 Myr old, it’s one of the youngest and longest-period super-puffy planets with measured stellar obliquity....

Also a possible giant planet may exist farther from the star...

Super-Earth L 98-59 d may be neither a gas dwarf nor a water world—its low density points to a volatile-rich magma ocean planet with an SO₂-H₂ atmosphere....

This Neptune-mass planet orbits a tilted red dwarf with a long-lived polar starspot, persisting for at least 7 years....

High escape velocity + low stellar activity however hint it may retain a secondary atmosphere. Further observation might show more....

If confirmed, its wide orbit defies core accretion theory, it could reshape how we think gas giants form....

WASP-94Abs misaligned orbit and JWST spectrum reveal a low C/O ratio and near-stellar metallicity. These traits hint it formed far out, accreted solids, then migrated inward. A clear step toward decoding hot Jupiter origins. WASP 94 is a binary star with exoplanets known to be orbiting both A and B components. The system is 687 light years away. ...

Its short 2.6-day orbit and tidal heating make it a rare probe of atmospheric loss and migration....

James Webb Space Telescope discovered water ice in a Kuiper belt analogue around young star HD 181327. The star has about 40 % more mass than the Sun and lies 158 light years away. The young star is probably bound to the close Eta Telescopii system. Astronomers found a cold debris disk 86 AU from the star....
