A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
Constraining disk evolution prescriptions of planet population synthesis models with observed disk masses and accretion rates
C. F. Manara, C. Mordasini, L. Testi +4
While planets are commonly discovered around main-sequence stars, the processes leading to their formation are still far from being understood. Current planet population synthesis…
Graze-and-Merge Collisions under External Perturbers
Alexandre Emsenhuber, Erik Asphaug
Graze-and-merge collisions (GMCs) are common multi-step mergers occurring in low-velocity off-axis impacts between similar sized planetary bodies. The first impact happens at somew…
The Exoplanet Population Observation Simulator. II -- Population Synthesis in the Era of Kepler
Gijs D. Mulders, Christoph Mordasini, Ilaria Pascucci +3
The collection of planetary system properties derived from large surveys such as Kepler provides critical constraints on planet formation and evolution. These constraints can only…
Fate of the runner in hit-and-run collisions
Alexandre Emsenhuber, Erik Asphaug
In similar-sized planetary collisions, a significant part of the impactor often misses the target and continues downrange. We follow the dynamical evolution of "runners" from giant…
Realistic On-The-Fly Outcomes of Planetary Collisions: Machine Learning Applied to Simulations of Giant Impacts
Saverio Cambioni, Erik Asphaug, Alexandre Emsenhuber +3
Planet formation simulations are capable of directly integrating the evolution of hundreds to thousands of planetary embryos and planetesimals, as they accrete pairwise to become p…
Hints for a Turnover at the Snow Line in the Giant Planet Occurrence Rate
Rachel B. Fernandes, Gijs D. Mulders, Ilaria Pascucci +2
The orbital distribution of giant planets is crucial for understanding how terrestrial planets form and predicting yields of exoplanet surveys. Here, we derive giant planets occurr…
