The fragility of the Uranian moons during the giant planet instability
Matthew S. Clement, Nathan A. Kaib, Andre Izidoro +1
It is thought that, sometime after their formation, the solar system's giant planets experienced a dynamical instability that caused their orbits to excite, diverge, and ejected on…
Elevated Eccentricities in the Radius Valley Hint at Water-Rich Mini-Neptunes
Sho Shibata, Andre Izidoro
While recent planet-formation models broadly reproduce the observed population of super-Earths and mini-Neptunes, as well as the bimodal radius distribution (the ``radius valley'')…
The Role of Magnetospheric Rebound in Breaking Resonant Chains of Super-Earths and Mini-Neptunes
Mengrui Pan, Andre Izidoro, Sho Shibata
Stellar magnetic fields are thought to truncate the inner regions of protoplanetary disks around T Tauri stars, creating a magnetospheric cavity near the star. As the disk evolves…
Very-wide-orbit planets from dynamical instabilities during the stellar birth cluster phase
André Izidoro, Sean N. Raymond, Nathan A. Kaib +2
Gas giant planets have been detected on eccentric orbits several hundreds of astronomical units in size around other stars. It has been proposed that even the Sun hosts a wide-orbi…
A tale of dynamical instabilities and giant impacts in the radius valley
Sho Shibata, Andre Izidoro
The size distribution of planets with radii between 1 and peaks near 1.4 and , with a dip around -- the so-called "radius valley." Recent s…
Size-Frequency Distribution of Terrestrial Leftover Planetesimals and S-complex Implanted Asteroids
Rogerio Deienno, Andre Izidoro, David Nesvorny +3
The isotopic composition of meteorites linked to S-complex asteroids has been used to suggest that these asteroids originated in the terrestrial planet's region, i.e., within 1.5 a…
