Evolution of Main Sequence Stars Transferring Mass to a Supermassive Black Hole
Andrey Sandomirsky, Re'em Sari, Aleksandra Olejak +1
We consider main-sequence stars orbiting close to a supermassive black hole (SMBH), which are potential gravitational wave (GW) sources for LISA if their orbital periods are of the…
Emission line formation in scattering dominated media: implications for LRDs
Elisha Modelevsky, Omri Nitzan, Re'em Sari +1
Recent JWST observations of ``Little Red Dots'' (LRDs) reveal broad and prominent Balmer emission lines. We present a theoretical framework for intrinsic emission line formation an…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
Tracking S-star cluster orbits around Sgr A* calibrates orbital transport models for space-borne gravitational wave detectors. Standard kinetic theories model this cluster via loca…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
Stellar trajectories around the Galactic Center provide a testing environment for general relativity. The intrinsic rotation of these stars evolves under covariant transport in cur…
Dynamics in Nuclear Stellar Clusters: The Impact of Collisions and Disrupted Binaries
Barak Rom, Re'em Sari
The nuclear stellar clusters surrounding supermassive black holes (SMBHs) host millions of stars and stellar remnants. We study how stellar collisions and binary disruptions, along…
Evolution of Stars During the Main Sequence and the Transition to the Red Giant Phase
Ravid Achituv, reem sari
We derive a simple analytical description for the structure and evolution of -- stars throughout main-sequence hydrogen burning. We obtain an analytical relation for…
The - Relation Has to Break
Omri Nitzan, Re'em Sari
We revisit the growth of central black holes via tidal disruption events (TDEs) and plunges of stellar-mass black holes (sBHs). Our model incorporates the current understanding of…
Transonic Solutions for Recombination-Driven Stellar Winds
Ilan Strusberg, Re'em Sari, Jim Fuller
We present an analytical stationary isentropic solution of the spherically symmetric Euler equations in the gravitational field of a star using an equation of state of ionizable mo…
