[astro-ph.EP] Ultra-short-period (USP) rocky exoplanets can have dayside temperatures high enough to maintain permanent magma oceans, sitting at the intersection of interior geophysics and atmospheric chemistry. Coupled feedbacks between the […]

PALEOS: Multiphase Equations of State and Mass-Radius Relations for Exoplanet Interiors
Modeling the interior of a rocky or water-rich exoplanet is a thermodynamic closure problem: every layer’s density, temperature gradient, and phase must follow from an equation of state (EoS) that […]

Probing Atmospheric Escape Through Metastable He I Triplet Lines In 15 Exoplanets Observed With SPIRou
For several years, the metastable helium triplet line has been successfully used as a tracer to probe atmospheric escape in transiting exoplanets. This absorption in the near-infrared (1083.3 nm) can […]
