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…
The Distribution of Planet Radius in Kepler Multiplanet Systems Depends on Gap Complexity
David R. Rice, Jason H. Steffen, Allona Vazan
The distribution of small planet radius (4 R) is an indicator of the underlying processes governing planet formation and evolution. We investigate the correlation betwe…
The TESS-Keck Survey. XVIII. A sub-Neptune and spurious long-period signal in the TOI-1751 system
Anmol Desai, Emma V. Turtelboom, Caleb K. Harada +37
We present and confirm TOI-1751 b, a transiting sub-Neptune orbiting a slightly evolved, solar-type, metal-poor star ( K, , V = 9.3 ma…
Composition constraints of the TRAPPIST-1 planets from their formation
Anna C. Childs, Cody Shakespeare, David R. Rice +2
We study the formation of the TRAPPIST-1 (T1) planets starting shortly after Moon-sized bodies form just exterior to the ice line. Our model includes mass growth from pebble accret…
Stable lifetime of compact, evenly-spaced planetary systems with non-equal masses
David R. Rice, Jason H. Steffen
Compact planetary systems with more than two planets can undergo orbital crossings from planet-planet perturbations. The time which the system remains stable without orbital crossi…
Confirming the 3:2 Resonance Chain of K2-138
Mariah G. MacDonald, Leonard Feil, Tyler Quinn +1
The study of orbital resonances allows for the constraint of planetary properties of compact systems. K2-138 is an early K-type star with six planets, five of which have been propo…
MAGRATHEA: an open-source spherical symmetric planet interior structure code
Chenliang Huang, David R. Rice, Jason H. Steffen
MAGRATHEA is an open-source planet structure code that considers the case of fully differentiated spherically symmetric interiors. Given the mass of each layer and the surface temp…
Implications of an improved water equation of state for water-rich planets
Chenliang Huang, David R. Rice, Zachary M. Grande +6
Water (HO), in all forms, is an important constituent in planetary bodies, controlling habitability and influencing geological activity. Under conditions found in the interio…
Survival of non-coplanar, closely-packed planetary systems after a close encounter
David R. Rice, Frederic A. Rasio, Jason H. Steffen
Planetary systems with more than two bodies will experience orbital crossings at a time related to the initial orbital separations of the planets. After a crossing, the system ente…
