Homepagetidal disruption gosixt-e kešandi Fr.: rupture par effet de marée The disruption of an extended astronomical object under the action of the → tidal forces exerted by another nearby object. → tidal; → disruption. |
tidal disruption event (TDE) ruydâd-e gosixt-e kešandi Fr.: événement de rupture par effet de marée The process in which a star is torn apart by the → tidal forces of a → supermassive black hole. About 50% of the star's mass is eventually → accreted by the → black hole, generating a flare, which, in extreme cases of very high (→ super-Eddington) mass → accretion rates, can result in a → relativistic jet. TDEs have been proposed as sources of → ultra-high-energy cosmic rays and suggested as sources of high energy astrophysical → neutrinos (W. Winter and C. Lunardini, 2021, Nature Astronomy, arXiv:2005.06097 and references therein). → tidal; → disruption; → event. |
tidal disruption flare âlâv-e gosixt-e kešandi Fr.: éruption A luminosity enhancement in the → light curve of a galaxy observed in X-rays or ultraviolet surveys supposed to be associated with the → tidal disruption of a star that has passed close to a → supermassive black hole in the core of a → host galaxy. An → accretion disk forms after the tidal disruption. The flare event marks the beginning of the accretion process onto the black hole. → tidal; → disruption; → flare. |
