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…
Stellar Black Hole Binary Mergers in Open Clusters
S. Rastello, P. Amaro-Seoane, M. Arca-Sedda +3
In this paper we study the evolution of a primordial black hole binary (BHB) in a sample of over 1500 direct-summation body simulations of small-and intermediate-size isolated…
Black hole and neutron star mergers in galactic nuclei
Giacomo Fragione, Evgeni Grishin, Nathan W. C. Leigh +2
Nuclear star clusters surrounding supermassive black holes (SMBHs) in galactic nuclei contain large numbers of stars, black holes (BHs) and neutron stars (NSs), a fraction of which…
Hypervelocity Stars from a Supermassive Black Hole-Intermediate-mass Black Hole binary
Alexander Rasskazov, Giacomo Fragione, Nathan W. C. Leigh +4
In this paper we consider a scenario where the currently observed hypervelocity stars in our Galaxy have been ejected from the Galactic center as a result of dynamical interactions…
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…
Intermediate-Mass Ratio Inspirals in Galactic Nuclei
Giacomo Fragione, Nathan Leigh
In this paper, we study the secular dynamical evolution of binaries composed of intermediate-mass and stellar-mass black holes (IMBHs and SBHs, respectively) in orbit about a centr…
