Star-disc interaction in galactic nuclei: orbits and rates of accreted stars
Gareth F. Kennedy, Yohai Meiron, Bekdaulet Shukirgaliyev +4
We examine the effect of an accretion disc on the orbits of stars in the central star cluster surrounding a central massive black hole by performing a suite of 39 high-accuracy dir…
Application of three-body stability to globular clusters: II. Observed velocity dispersions
Gareth F. Kennedy
The velocity dispersion profile in globular clusters (GCs) is explained here without having to rely on dark matter or a modification of Newtonian dynamics (MOND). The flattening of…
Application of three-body stability to globular clusters: I. The stability radius
Gareth F. Kennedy
The tidal radius is commonly determined analytically by equating the tidal field of the galaxy to the gravitational potential of the cluster. Stars crossing this radius can move fr…
Tidal disruptions of separated binaries in galactic nuclei
Pau Amaro-Seoane, M. Coleman Miller, Gareth F. Kennedy
Several galaxies have exhibited X-ray flares that are consistent with the tidal disruption of a star by a central supermassive black hole. In theoretical treatments of this process…
The star capture model for fueling quasar accretion disks
Gareth F. Kennedy, Jordi Miralda-Escudé, Juna A. Kollmeier
Although the powering mechanism for quasars is now widely recognized to be the accretion of matter in a geometrically thin disk, the transport of matter to the inner region of the…
Signatures of resonant terrestrial planets in long-period systems
Gareth F. Kennedy, Rosemary A. Mardling
The majority of extrasolar planets discovered to date have significantly eccentric orbits, some if not all of which may have been produced through planetary migration. During this…
