ASASSN-24fw: Candidate circumplanetary disk occultation of a main-sequence star
Nadia L. Zakamska, Gautham Adamane Pallathadka, Dmitry Bizyaev +24
Dusty disks around planetary and substellar companions in outer reaches of exo-planetary systems can be detected as long-lasting occultations, provided the observer is close to the…
The impact of internal versus external perturbations on close-in exoplanet architectures
Christina Schoettler, James E Owen
Young planetary systems are subjected to different dynamical effects that can influence their orbital structure over time. In systems with more than one planet, other planets can i…
The Gradient of Mean Molecular Weight Across the Radius Valley
Kevin Heng, James E. Owen, Meng Tian
Photo-evaporation shapes the observed radii of small exoplanets and constrains the underlying distributions of atmospheric and core masses. However, the diversity of atmospheric ch…
Blowin' in the non-isothermal wind: core-powered mass loss with hydrodynamic radiative transfer
William Misener, Matthäus Schulik, Hilke E. Schlichting +1
The mass loss rates of planets undergoing core-powered escape are usually modeled using an isothermal Parker-type wind at the equilibrium temperature, . However, the…
