Magnetic field strengths of hot giant exoplanets consistent with Solar System values

Julia V. Seidel, Vivien Parmentier, Bibiana Prinoth +29

Magnetic fields are ubiquitous in the universe. They play a key role in shaping the activity of stars, the habitability of rocky planets, and the long-term retention of planetary a…

Mantle Convection and Nightside Volcanism on Lava World K2-141 b

Tobias G. Meier, Claire Marie Guimond, Raymond T. Pierrehumbert +13

Ultra-short period lava worlds offer a unique window into the coupled evolution of planetary interior and atmospheres under extreme irradiation. In this study, we investigate the m…

A Thick Volatile Atmosphere on the Ultrahot Super-Earth TOI-561 b

Johanna K. Teske, Nicole L. Wallack, Anjali A. A. Piette +10

Ultrashort-period (USP) exoplanets -- with R and periods 1 day -- are expected to be stripped of volatile atmospheres by intense host star irradiation…

Geodynamics of super-Earth GJ 486b

Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +8

Many super-Earths are on very short orbits around their host star and, therefore, more likely to be tidally locked. Because this locking can lead to a strong contrast between the d…

Reliable Detections of Atmospheres on Rocky Exoplanets with Photometric JWST Phase Curves

Mark Hammond, Claire Marie Guimond, Tim Lichtenberg +9

The prevalence of atmospheres on rocky planets is one of the major questions in exoplanet astronomy, but there are currently no published unambiguous detections of atmospheres on a…
