Hot Jupiters as a research area focuses on close-in, gas giant exoplanets with orbital periods of a few days and strong stellar irradiation, used as laboratories for testing planet formation, migration, and atmospheric physics. Work in this field addresses mechanisms of inward migration (e.g., disk-driven vs. high-eccentricity pathways), tidal interactions, atmospheric escape, cloud and haze formation, chemical disequilibrium, and energy transport under extreme irradiation. Researchers combine transit, eclipse, and phase-curve observations with high-resolution spectroscopy and sophisticated radiative–convective and global circulation models to constrain compositions, temperature–pressure profiles, wind patterns, and the interaction of these planets with their host stars’ radiation and magnetic environments.
Sand clouds form every morning but clear up by nightfall on WASP-94A b, a well-studied gas giant in a constellation located nearly 700 light years away from Earth. Using data from the James Webb Space Telescope (JWST), research ...

Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally "lonely" hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that's had astronomers ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new "hot Jupiter" exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which ...
Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever ...
