Most disks show complex structures like rings and cavities, hinting at planet formation...

The ratio of carbon to oxygen suggests the planet formed close to its star...

The planets orbit is not perfectly aligned with the stars equator, but tilted at a sharp angle. This tilt, combined with the stars rapid rotation, causes the planets trajectory to slowly wobble over time, a phenomenon called nodal precession....

The first planet TOI 238 b is a super-Earth with 1.4 Earth radii and was discovered just last year. Newly discovered TOI 238 c with 2.2 radii could be a water-rich world....

The planet has a radius of 1.24 Earth radii, a mass of 2.53 Earth masses, and an equilibrium temperature of 996 degrees Kelvin. It is likely composed of a large iron core, a small rocky mantle, and a negligible atmosphere....

TRAPPIST-1 c receives almost the same bolometric flux as Venus. However JWST measurements show no sign of CO2 which is abundant in the atmosphere of our neighboring planet. According to a new study stellar winds cannot account for all the lost CO2. So astronomers believe that the planet was either born without significant CO2 atmosphere, or must have lost big portion of it through the escape of hydrogen. ...

WASP-77Ab likely formed in a disk with few planetesimals and underwent disk-free migration, starting within the CO ice line and ending beyond the water ice line...

The exoplanet joins a growing census of aligned warm Jupiters around single stars....

HD 88986 b has the longest orbital period among known transiting planets with known mass and less than 4 Earth radii....
