Forcible division into pieces of an object. → tidal disruption.
From L. disruptio "a breaking asunder," noun of action from p.p. stem of disrumpere "break apart, split, shatter, break to pieces," from → dis- "apart" + rumpere "to break."
Gosixt, past stem of gosixtan "to tear away, to beark off."
Fr.: rupture dynamique
The process whereby a → bound system, such as a → binary system or a → globular cluster, is broken apart.
→ dynamical; → disruption.
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
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.
