Semi-Analytical Model for the Evolution of Stellar Binaries in the Empty Loss Cone of Massive Black Holes
Samuel McGuire, Evgeni Grishin, Ilya Mandel +1
Binary star systems orbiting close to a supermassive black hole (SMBH) evolve through encounters with other stars, the SMBH's tidal forces, and the binary's internal dynamics, incl…
Modern tidal interaction models for rapid binary population synthesis: II. Binary black hole formation, mergers, and spins
Veome Kapil, Ilya Mandel, Jeff Riley +3
We present predictions for the merger rates and effective spin () distribution of binary black holes (BBHs) from isolated binary evolution, using a new self-consisten…
Modern tidal interaction models for rapid binary population synthesis: I. Methods
Veome Kapil, Ilya Mandel, Evgeni Grishin +3
In this work, we present an updated prescription of contemporary tidal dissipation theory adapted for rapid binary population synthesis. Our simplified expressions encode the depen…
Extensions of Brown Hamiltonian-III. Applications to irregular satellites of giant planets
Hanlun Lei, Xiaoyan Leng, Evgeni Grishin
Irregular satellites, orbiting at large distances from their host planets, are subject to strong solar perturbations that render long-term orbital predictions particularly challeng…
A benchmark for binary star interaction with a supermassive black hole in general relativity
Megha Sharma, Alexander Heger, Daniel J. Price +4
Most galaxies have supermassive black holes (SMBH) at their centres, surrounded by stars with binary systems also present in this environment. We use two schemes - post-Newtonian (…
Sub-Snowline Formation of Gas-Giant Planets in Binary Systems
Ilay Kamai, Hagai B. Perets, Jakob Stegmann +1
Gas-giant planets are thought to require conditions beyond the water snow line to build solid cores efficiently. In close binary star systems, the companion's gravity additionally…
