Quasi-secular evolution of mildly hierarchical triple systems: analytics and applications for GW-sources and hot Jupiters
Evgeni Grishin, Hagai B. Perets, Giacomo Fragione
In hierarchical triple systems, the inner binary is perturbed by a distant companion. For large mutual inclinations, the Lidov-Kozai mechanism secularly excites large eccentricity…
The role of multiple giant impacts in the formation of the Earth-Moon system
Robert I. Citron, Hagai B. Perets, Oded Aharonson
The Earth-Moon system is suggested to have formed through a single giant collision, in which the Moon accreted from the impact-generated debris disk. However, such giant impacts ar…
Gas-Assisted Growth of Protoplanets in a Turbulent Medium
M. M. Rosenthal, R. A. Murray-Clay, H. B. Perets +1
Pebble accretion is a promising process for decreasing growth timescales of planetary cores, allowing gas giants to form at wide orbital separations. However, nebular turbulence ca…
Statistical Trends in the Obliquity Distribution of Exoplanet Systems
Diego J. Muñoz, Hagai B. Perets
Important clues on the formation and evolution of planetary systems can be inferred from the stellar obliquity . We study the distribution of obliquities using the California-Ke…
Moonfalls: Collisions between the Earth and its past moons
Uri Malamud, Hagai B. Perets, Christoph Schafer +1
During the last stages of the terrestrial planet formation, planets grow mainly through giant-impacts with large planetary embryos. The Earth's Moon was suggested to form through o…
Planet seeding through gas-assisted capture of interstellar objects
Evgeni Grishin, Hagai B. Perets, Yael Avni
Planet formation begins with collisional growth of small planetesimals accumulating into larger ones. Such growth occurs while planetesimals are embedded in a gaseous protoplanetar…
