Weighing potentially habitable planets around Sun-like stars remains surprisingly difficult: a methods test found that precise measurements often require planets weighing about 8 to 10 Earth masses. The latest reports also explore brilliant radio bursts from a rapidly spinning brown dwarf, a possible hotspot on another brown dwarf, and how transit changes can expose a planet that never crosses its star.

The most promising ways to confirm Gaia astrometric planetary candidates and obtain follow-up data

Image: The most promising ways to confirm Gaia astrometric planetary candidates and obtain follow-up data
Astrometric planet candidates around white dwarfs can be confirmed and characterized by combining astrometric data with spectroscopic and photometric data. Radial velocity and infrared photometry can be used to probe the mass of the objects producing some of the astrometric signals, and rule out parts of the brown dwarf and planet mass parameter space....

Exoplanet Kepler 1513 b was discovered in 2016. Observed transit timing variations were thought to be originating in planet-moon interaction. New observations show that better explanation for the variations is an existence of a second, non-transiting planet in the system....

Image: Stellar companions can affect planet formation
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....

Image: JWST found heavy elements in atmosphere of exoplanet HD 209458 b
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....

Image: Habitable zone stability probed within the HD 141399 system with 4 giant exoplanets
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....

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....
