GSN 069 – A tidal disruption near miss [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2020
ABSTRACT I suggest that the quasi-periodic ultrasoft X-ray eruptions recently observed from the galaxy GSN 069 may result from accretion from a low-mass white dwarf in a highly eccentric orbit about its central black hole. At $0.21\,\rm M_{\odot }$, this star was probably the core of a captured red giant.

Tidal flares and rates from an archival cluster survey

EPJ Web of Conferences, 2012
Tidal disruption flares (TDFs) are potent indicators of the co-evolution of galaxies and the massive black holes (MBHs) which they host in their nuclei, both in terms of the individual black holes revealed by tidal flares and in terms of the overall ...

Modelling the light-curves of objects tidally disrupted by a black hole

, 2009
Tidal disruption by massive black holes is a phenomenon, during which a large part of gravitational energy can be released on a very short time-scale. The time-scales and energies involved during X-ray and IR flares observed in Galactic centre suggest ...

Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles

Galaxies, 2016
Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

The Tidal Disruption of Giant Stars and Their Contribution to the Flaring Supermassive Black Hole Population

, 2012
Sun-like stars are thought to be regularly disrupted by supermassive black holes (SMBHs) within galactic nuclei. Yet, as stars evolve off the main sequence their vulnerability to tidal disruption increases drastically as they develop a bifurcated ...

A New Way to Detect Massive Black Holes in Galaxies: The Stellar Remnants of Tidal Disruption [PDF]

, 2001
We point out that the tidal disruption of a giant may leave a luminous (10^35-10^39 ergs/s), hot (10-100 eV) stellar core. The ``supersoft'' source detected by Chandra at the center of M31 may be such a core; whether or not it is, the observations have ...

Ultraviolet and optical observations of tidal disruption events

EPJ Web of Conferences, 2012
Tidal disruption events are expected to produce a luminous flare of radiation from fallback accretion of tidally disrupted stellar debris onto the central supermassive black hole.
