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....

Barnard's Star is now one of the most compact low-mass planetary systems known. Barnard's Star is a small red dwarf only 6 light years away from the Solar System. One confirmed planet and two candidates orbiting the star were already known. New observations now confirm the three objects and add a new one....

It’s one of the coolest directly imaged exoplanets ever, with hints of exotic chemistry in its atmosphere. ...

It’s the closest confirmed ultra-short-period planet to Earth’s size, with no thick atmosphere. The planet TOI 6324 b orbits a nearby (67 light years) red dwarf star with about 20 % solar mass. The planet's orbit is so tight, that the year on it lasts less than a day. Although the planet is similar in size and mass to Earth, its proximity to the star expose it to extreme temperature and radiation....

CE Antliae is a very young variable star of T Tauri class, meaning it is still in process of contracting to become the main sequence. There are multiple known rings orbiting the star. The position of newly discovered planet candidate may explain the unique rings around the star. ...

These molecules suggest intense vertical mixing in the atmosphere, challenging previous models of carbon chemistry in cold brown dwarfs. WISE J0458+6434 is a binary system with two T-type brown dwarfs separated by several AU. The pair lies 30 light years away....
