Rocky histories: The effect of high excitations on the formation of rocky planets

Jennifer Scora, Diana Valencia, Alessandro Morbidelli +1

Rocky planets both in and outside of our solar system are observed to have a range of core-mass fractions (CMFs). Imperfect collisions can preferentially strip mantle material from…

Simple physics and integrators accurately reproduce Mercury instability statistics

Dorian S. Abbot, David M. Hernandez, Sam Hadden +3

The long-term stability of the Solar System is an issue of significant scientific and philosophical interest. The mechanism leading to instability is Mercury's eccentricity being p…

TOI-561 b: A Low Density Ultra-Short Period "Rocky" Planet around a Metal-Poor Star

Casey Brinkman, Lauren M. Weiss, Fei Dai +22

TOI-561 is a galactic thick disk star hosting an ultra-short period (0.45 day orbit) planet with a radius of 1.37 R, making it one of the most metal-poor ([Fe/H] = -0.41…

TOI-1452 b: SPIRou and TESS reveal a super-Earth in a temperate orbit transiting an M4 dwarf

Charles Cadieux, René Doyon, Mykhaylo Plotnykov +53

Exploring the properties of exoplanets near or inside the radius valley provides insights on the transition from the rocky super-Earths to the larger, hydrogen-rich atmosphere mini…
