Stellar Energy Relaxation around A Massive Black Hole
Ben Bar-Or, Gábor Kupi, Tal Alexander
[abridged] Energy relaxation around a massive black hole (MBH) is key to establishing the dynamical state of galactic nuclei, and the nature of close stellar interactions with the…
Galactic rotation curves in brane world models
L. Á. Gergely, T. Harko, M. Dwornik +2
In the braneworld scenario the four dimensional effective Einstein equation has extra source terms, which arise from the embedding of the 3-brane in the bulk. These non-local effec…
Dynamical evolution of the young stars in the Galactic center: N-body simulations of the S-stars
Hagai B. Perets, Alessia Gualandris, Gabor Kupi +2
We use N-body simulations to study the evolution of the orbital eccentricities of stars deposited near (<0.05 pc) the Milky Way massive black hole (MBH), starting from initial cond…
Dynamical evolution of the young stars in the Galactic center
Hagai. B. Perets, Alessia Gualandris, David Merritt +1
Recent observations of the Galactic center revealed a nuclear disk of young OB stars near the massive black hole (MBH), in addition to many similar outlying stars with higher eccen…
The efficiency of resonant relaxation around a massive black hole
Ehud Eilon, Gábor Kupi, Tal Alexander
Resonant relaxation (RR) is a rapid relaxation process that operates in the nearly-Keplerian potential near a massive black hole (MBH). RR dominates the dynamics of compact remnant…
Determination of the upper and lower bound of masslimit of degenerate fermionic dark matter objects
Gábor Kupi
We give a gravitational upper limit for the mass of static degenerate fermionic dark matter objects. The treatment we use includes fully relativistic equations for describing the s…
