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…
Comparing the Architectures of Multiplanet Systems from Kepler, K2, and TESS Data
Robert Royer, Jason H. Steffen
Exoplanet surveys like Kepler, TESS, and K2 have shown that planetary systems are common in our galaxy. These surveys, along with several others, have identified thousands of plane…
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…
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…
Enhanced Stability in Planetary Systems with Similar Masses
Dong-Hong Wu, Sheng Jin, Jason H. Steffen
This study employs numerical simulations to explore the relationship between the dynamical instability of planetary systems and the uniformity of planetary masses within the system…
