Searching for GEMS: TOI-6383Ab, a Giant Planet Transiting an M3-dwarf Star in a Binary System
The Astronomical JournalWe report on the discovery of a transiting giant planet around the 3500 K M3-dwarf star TOI-6383A located 172 pc from Earth. It was detected by the Transiting Exoplanet Survey Satellite and confirmed by a combination of ground-based follow-up photometry ...

Self Similar Shocks in Atmospheric Mass Loss Due to Planetary Collisions
Atmosphere, 2020 We present a mathematical model for the propagation of the shock waves that occur during planetary collisions. Such collisions are thought to occur during the formation of terrestrial planets, and they have the potential to erode the planet’s atmosphere.

Formation of Ultra-short-period Planets in Hot Jupiter Systems: Application to WASP-47
The Astrophysical Journal LettersThe WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as the innermost planetary companion.

Quantifying External Energy Inputs for Giant Planet Magnetospheres
Geophysical Research LettersThe long‐standing “energy crisis” at the giant planets refers to the anomalous heating of planetary thermospheres compared to the available energy from solar irradiance. The coupling between planetary magnetospheres and their upper atmospheres is thought

Looking into the Giant Planets [PDF]
Science, 2004 Jupiter and Saturn are mostly made up of hydrogen and helium, but details of their precise composition and the evolution and structure of their interiors are hard to come by. In his Perspective, Fortney highlights recent model studies that have shed light on the likely structure and evolution of these giant planets.

Most High-density Exoplanets Are Unlikely to Be Remnant Giant Planet's Cores
The Astrophysical Journal LettersSome exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories—metal-rich formation hypothesis and naked core hypothesis—that explain how formation and evolution can alter the ...

Tidal Dissipation in Giant Planets
Space Science ReviewsAbstractTidal interactions between moons and planets can have major effects on the orbits, spins, and thermal evolution of the moons. In the Saturn system, tidal dissipation in the planet transfers angular momentum from Saturn to the moons, causing them to migrate outwards.
