Hyper-velocity and tidal stars from binaries disrupted by a massive Galactic black hole
@article{Hills1988HypervelocityAT, title={Hyper-velocity and tidal stars from binaries disrupted by a massive Galactic black hole}, author={JACK G. Hills}, journal={Nature}, year={1988}, volume={331}, pages={687-689}, url={https://api.semanticscholar.org/CorpusID:4250308}}A close but newtonian encounter between a tightly bound binary and a 106 M⊙ black hole causes one binary component to become bound to the black hole and the other to be ejected at up to 4,000 km−1. The discovery of even one such hyper-velocity star coming from the Galactic centre would be nearly definitive evidence for a massive black hole. The new companion of the black hole has a high orbital velocity which increases further as its orbit shrinks by tidal dissipation. The gravitational energy…

BINARY DISRUPTION BY MASSIVE BLACK HOLES: HYPERVELOCITY STARS, S STARS, AND TIDAL DISRUPTION EVENTS
- B. BromleyS. KenyonM. GellerWarren R. Brown
- 2012
Physics
We examine whether disrupted binary stars can fuel black hole growth. In this mechanism, tidal disruption produces a single hypervelocity star (HVS) ejected at high velocity and a former companion…
DOUBLE TIDAL DISRUPTIONS IN GALACTIC NUCLEI
A star on a nearly radial trajectory approaching a massive black hole (MBH) gets tidally disrupted if it comes sufficiently close to the MBH. Here we explore what happens to binary stars whose…
Hypervelocity Binary Stars: Smoking Gun of Massive Binary Black Holes
- Youjun LuQingjuan YuD.N.C. Lin

Physics
The hypervelocity stars recently found in the Galactic halo are expelled from the Galactic center through interactions between binary stars and the central massive black hole or between single stars…
Hydrodynamical simulations of the tidal stripping of binary stars by massive black holes
- D. MainettiA. LupiS. CampanaM. Colpi

Physics
In a galactic nucleus, a star on a low angular momentum orbit around the central massive black hole can be fully or partially disrupted by the black hole tidal field, lighting up the compact object…
High-velocity stars from the interaction of a globular cluster and a massive black hole binary

Physics
High velocity stars are stars moving at velocities so high to require an acceleration mechanism involving binary systems or the presence of a massive central black hole. In the frame of a galaxy…
A Stream of Hypervelocity Stars from the Galactic Center
- A. Generozov

Physics
Recent observations have found a 1700 km s−1 star [S5-HVS1] that was ejected from the Galactic center approximately five million years ago. This star was likely produced by the tidal disruption of a…
A new rare type of supernovae: hypervelocity stellar collisions at galactic centers
When a binary star system is tidally disrupted by a supermassive black hole at a galactic nucleus, one star is ejected at a high speed while the other remains in a tightly bound orbit around the…
Binary Disruption by Massive Black Holes in Globular Clusters
- E. Pfahl
- 2005
Physics
A massive (~102-104 M☉) black hole at the center of a globular cluster will tidally disrupt binaries that pass sufficiently close. Such an encounter results in the capture of one binary component by…
Tidal disruption of stars by black holes of 106–108 solar masses in nearby galaxies
- M. Rees
- 1988
Physics
Stars in galactic nuclei can be captured or tidally disrupted by a central black hole. Some debris would be ejected at high speed', the remainder would be swallowed by the hole, causing a bright…
THE PROPERTIES OF HYPERVELOCITY STARS AND S-STARS ORIGINATING FROM AN ECCENTRIC DISK AROUND A SUPERMASSIVE BLACK HOLE
Hypervelocity stars (HVSs), which are observed in the Galactic halo, are believed to be accelerated to large velocities by a process of tidal disruption of binary stars passing close to the…

The 2.0-2.4 micron spectra, with 120 km/s resolution, obtained for six late-type stars within 2 pc of the center of the Galaxy were used to derive spectral types and reddenings for these stars. The…
