Outstanding Questions in Giant Planet Theory
Ravit Helled
Giant planets have key role in shaping planetary systems. Their composition reveals information on the conditions at which planets form, and their interiors serve as natural labora…
Origin and characterization of super-Earths and sub-Neptunes
Léna Parc, Julia Venturini, François Bouchy +6
Super-Earths and sub-Neptunes represent the most common class of exoplanets discovered to date in our galaxy, yet they have no direct analogues in the Solar System. Since 2014, res…
Giant Planet Formation by Disk Instability
Ravit Helled, Oliver Schib, Christian Reinhardt +4
The disk instability (DI) model for giant planet formation remains an attractive alternative in explaining the formation of giant planets at early times, giant planets at large rad…
Recent advances in modelling of global-scale collisions using smoothed particle hydrodynamics
Christian Reinhardt, Sabina D. Raducan, Thomas Meier +3
Impacts play a fundamental role in shaping the physical and chemical properties of the objects in our Solar System. Given the challenges in replicating such collisions through labo…
GEMS JWST: HATS-75 b -- A giant planet with a sub-solar metallicity atmosphere orbiting an M-dwarf
Reza Ashtari, Jacob Lustig-Yaeger, Jessica Libby-Roberts +12
HATS-75 b is one of the recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) with a transmission spectrum shaped by both its atmosphere and the active stellar surface…
GEMS JWST: A sub-Solar metallicity atmosphere for giant planet TOI-5293Ab orbiting a rapidly changing M-dwarf
Shubham Kanodia, Caleb I. Cañas, Jacob Lustig-Yaeger +13
The growing sample of Giant Exoplanets around M-dwarf Stars (GEMS) helps probe the extremes of giant planet formation. Comparing the properties of this sample with their FGK counte…
