Dynamical origin of S-type planets in close binary stars
Giacomo Fragione
Understanding the origin of planets that have formed in binary stars is fundamental to constrain theories of binary and planet formation. The planet occurrence rate in binaries wit…
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…
A dynamical origin for planets in triple star systems
Giacomo Fragione, Abraham Loeb, Idan Ginsburg
Recent radial velocity and transit data discovered planets in binary or triple stellar systems out of the entire population of a few thousand known planets. Stellar comp…
Transits Probabilities Around Hypervelocity and Runaway Stars
Giacomo Fragione, Idan Ginsburg
In the blooming field of exoplanetary science, NASA's Kepler Space Telescope has revolutionized our understanding of exoplanets. Kepler's very precise and long-duration photometry…
