Lightning Bolts On Jupiter Pack More Than 100 Times The Power Of Earth’s Flashes
Jupiter, the most massive planet in our solar system, has correspondingly humongous storms, some of which last for centuries. Some of these storms also generate terrific bolts of lightning, according […]

Gemini South Confirms Long-Suspected Link Between the Composition of Exoplanets and Their Host Stars
Almost 320 light-years away in the Libra constellation lies WASP-189b, an exoplanet known as an ultra-hot Jupiter (UHJ). UHJs have temperatures high enough to vaporize rock-forming elements like magnesium (Mg), […]

Deep Radiative Zones Affect The Planetary Cooling And Internal Structure: Implications For Exoplanet Characterisation
The thermal evolution and interior structure of giant exoplanets are sensitive to the treatment of radiative opacity. At temperatures of ~2000 K, depletion of alkali metals can create a window […]

A Universal Brown Dwarf Desert Formed Between Planets And Star
Giant planets and brown dwarfs play a crucial role in star and planet formation, as they are situated at the boundary between planets and stars with uncertain formation mechanisms.

The Orbital Eccentricity–Radius Distribution for Warm, Single Planets in TESS
We characterize the radius-dependent eccentricity distribution of 347 warm (P = 8-200 days) systems with only one transiting planetary candidate identified during Sectors 1-69 of the TESS mission.

TESS Planets In Known Radial Velocity Cold Jupiter Systems: Hot Super Earth Occurrence Is Enhanced By Cold Jupiters
The correlation between inner super-Earths (SEs) and outer cold Jupiters (CJs) provides an important constraint on the formation and dynamical evolution of planetary systems. Previous studies have suggested a positive […]
