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…
Milky Way potentials in CDM and MOND. Is the Large Magellanic Cloud on a bound orbit?
Xufen Wu, Benoit Famaey, Gianfranco Gentile +2
We compute the Milky Way potential in different cold dark matter (CDM) based models, and compare these with the modified Newtonian dynamics (MOND) framework. We calculate the axis…
Runaway and hypervelocity stars in the Galactic halo: Binary rejuvenation and triple disruption
Hagai B. Perets
Young stars observed in the distant Galactic halo are usually thought to have formed elsewhere, either in the Galactic disk or perhaps the Galactic center, and subsequently ejected…
Dynamical and evolutionary constraints on the nature and origin of hypervelocity stars
Hagai B. Perets
In recent years several hypervelocity stars (HVSs) have been observed in the halo of our Galaxy. Such stars are thought to be ejected through dynamical interactions near the massiv…
Getting a kick out of the stellar disk(s) in the galactic center
Hagai B. Perets, Gabor Kupi, Tal Alexander
Recent observations of the Galactic center revealed a nuclear disk of young OB stars, in addition to many similar outlying stars with higher eccentricities and/or high inclinations…
Temperature fluctuations of interstellar dust grains
Kobi Horn, Hagai B. Perets, Ofer Biham
The temperatures of interstellar dust grains are analyzed using stochastic simulations, taking into account the grain composition and size and the discreteness of the photon flux.…
