Architectures of Exoplanetary Systems. IV: A Multi-planet Model for Reproducing the Radius Valley and Intra-system Size Similarity of Planets around Kepler's FGK Dwarfs
Matthias Y. He, Eric B. Ford
The Kepler-observed distribution of planet sizes have revealed two distinct patterns: (1) a radius valley separating super-Earths and sub-Neptunes and (2) a preference for intra-sy…
Biases from Missing a Small Planet in High Multiplicity Systems
C. Alexander Thomas, Lauren M. Weiss, Matthias Y. He
In an era when we are charting multiple planets per system, one might wonder the extent to which "missing" (or failing to detect) a planet can skew our interpretation of the system…
From Stability to Instability: Characterizing the Eccentricities of Multi-planet Systems in the California Kepler Survey as a Means of Studying Stability
Matthew J. Doty, Lauren M. Weiss, Matthias Y. He +1
Understanding the stability of exoplanet systems is crucial for constraining planetary formation and evolution theories. We use the machine-learning stability indicator, SPOCK, to…
Developing a Drift Rate Distribution for Technosignature Searches of Exoplanets
Megan G. Li, Sofia Z. Sheikh, Christian Gilbertson +4
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a "drift rate''. For a transmission from…
Beyond 2-D Mass-Radius Relationships: A Nonparametric and Probabilistic Framework for Characterizing Planetary Samples in Higher Dimensions
Shubham Kanodia, Matthias Y. He, Eric B. Ford +2
Fundamental to our understanding of planetary bulk compositions is the relationship between their masses and radii, two properties that are often not simultaneously known for most…
Inner Planetary System Gap Complexity is a Predictor of Outer Giant Planets
Matthias Y. He, Lauren M. Weiss
The connection between inner small planets and outer giant planets is crucial to our understanding of planet formation across a wide range of orbital separations. While Kepler prov…
Debiasing the Minimum-Mass Extrasolar Nebula: On the Diversity of Solid Disk Profiles
Matthias Y. He, Eric B. Ford
A foundational idea in the theory of in situ planet formation is the "minimum mass extrasolar nebula" (MMEN), a surface density profile () of disk solids that is necessary to fo…
Edge-of-the-Multis: Evidence for a Transition in the Outer Architectures of Compact Multi-Planet Systems
Sarah C. Millholland, Matthias Y. He, Jon K. Zink
Although the architectures of compact multiple-planet systems are well-characterized, there has been little examination of their "outer edges", or the locations of their outermost…
Evidence for a Non-Dichotomous Solution to the Kepler Dichotomy: Mutual Inclinations of Kepler Planetary Systems from Transit Duration Variations
Sarah C. Millholland, Matthias Y. He, Eric B. Ford +3
Early analyses of exoplanet statistics from the Kepler Mission revealed that a model population of multiple-planet systems with low mutual inclinations (…
Friends and Foes: Conditional Occurrence Rates of Exoplanet Companions and their Impact on Radial Velocity Follow-up Surveys
Matthias Y. He, Eric B. Ford, Darin Ragozzine
Population studies of Kepler's multi-planet systems have revealed a surprising degree of structure in their underlying architectures. Information from a detected transiting planet…
Architectures of Exoplanetary Systems. III: Eccentricity and Mutual Inclination Distributions of AMD-stable Planetary Systems
Matthias Y. He, Eric B. Ford, Darin Ragozzine +1
The angular momentum deficit (AMD) of a planetary system is a measure of its orbital excitation and a predictor of long-term stability. We adopt the AMD-stability criteria to const…
Architectures of Exoplanetary Systems. II: An Increase in Inner Planetary System Occurrence Toward Later Spectral Types for Kepler's FGK Dwarfs
Matthias Y. He, Eric B. Ford, Darin Ragozzine
The Kepler mission observed thousands of transiting exoplanet candidates around hundreds of thousands of FGK dwarf stars. He, Ford, & Ragozzine (2019) (arXiv:1907.07773) applied fo…
Architectures of Exoplanetary Systems. I: A Clustered Forward Model for Exoplanetary Systems around Kepler's FGK Stars
Matthias Y. He, Eric B. Ford, Darin Ragozzine
Observations of exoplanetary systems provide clues about the intrinsic distribution of planetary systems, their architectures, and how they formed. We develop a forward modelling f…
On the stability and collisions in triple stellar systems
Matthias Y. He, Cristobal Petrovich
A significant fraction of main sequence stars are part of a triple system. We study the long-term stability and dynamical outcomes of triple stellar systems using a large number of…
First limits on the occurrence rate of short-period planets orbiting brown dwarfs
Matthias Y. He, Amaury H. M. J. Triaud, Michaël Gillon
Planet formation theories predict a large but still undetected population of short-period terrestrial planets orbiting brown dwarfs. Should specimens of this population be discover…
