Study of 66 stars with planets and planet candidates found that those with stellar companions have more false positive planet detections and shorter orbital periods for their planets. This suggests that stellar companions can truncate planet-forming disks and affect planet formation....

JWST has observed the atmosphere of HD 209458b, a hot Jupiter exoplanet. The observations reveal that the planet has a super-solar metallicity and a very low C/O ratio, suggesting that it has undergone significant contamination by evaporating planetesimals while migrating inward....

K-dwarf star HD 141399 is about 120 light years away and there are 4 known exoplanets orbiting it. All of them are gas giants similar to Jupiter and one is suspected to reside in the habitable zone of the star....

The planet closer to the star is the first warm exo-Saturn with a precisely determined mass and radius...

Astronomers have studied the atmosphere of a newly discovered planet-mass companion to a young star. They find that its carbon-to-oxygen ratio is consistent with it forming like a star, rather than like a planet....

Astronomers led by Stephanie Yoshida announced discovery of a new super-puff exoplanet. It orbits a Sun-like star TOI 1420 once in every 7 days. With 12 Earth radii and 25 Earth masses it has only 1 % of Earths density....

Average density of the super-Earth HIP 113103 b is very similar to that of Earth, but the planet is 6 times heavier....

Radial velocity measurement shows clear signs of three exoplanets in the system. All bigger than Earth....

The star is part of a binary system almost 4 thousand light years away....
