Building Wet Planets through High-Pressure Magma-Hydrogen Reactions
Harrison Horn, Allona Vazan, Stella Chariton +2
Close-in transiting sub-Neptunes are abundant in our galaxy \cite{fulton2017california}. Planetary interior models based on their observed radius-mass relationship suggest that sub…
Magrathea v2: A planetary interior modeling platform in C++
David R. Rice, Chenliang Huang, Robert Royer +5
Magrathea is an open-source C++ code for modeling the internal structure of differentiated planets. The initial release, Huang et al. (2022), introduced the base solver, a modular…
A metal-poor atmosphere with a hot interior for a young sub-Neptune progenitor: JWST/NIRSpec transmission spectrum of V1298 Tau b
Saugata Barat, Jean-Michel Désert, Sagnick Mukherjee +19
We present the JWST/NIRSpec G395H transmission spectrum of the young (10 - 20 Myr old) transiting planet V1298 Tau b (9.85+/-0.35 Re, Teq=670K). Combined HST and JWST observations…
Effect of Galactic Chemical Evolution on Exoplanet Properties
Jason H. Steffen, Cody Shakespeare, Robert Royer +2
We couple a simplified model for the galactic chemical evolution, with software that models the condensation of dust in protoplanetary disks and software that models the interior s…
A Terminology and Quantitative Framework for Assessing the Habitability of Solar System and Extraterrestrial Worlds
Daniel Apai, Rory Barnes, Matthew M. Murphy +13
The search for extraterrestrial life in the Solar System and beyond is a key science driver in astrobiology, planetary science, and astrophysics. A critical step is the identificat…
Uncertainties in the Inference of Internal Structure: The Case of TRAPPIST-1 f
David R. Rice, Chenliang Huang, Jason H. Steffen +1
We use the TRAPPIST-1 system as a model observation of Earth-like planets. The densities of these planets being 1-10% less than the Earth suggest that the outer planets may host si…
