Repeating Partial Tidal Encounters of Sun-like Stars Leading to Their Complete Disruption

open access: yesThe Astrophysical Journal
Stars grazing supermassive black holes on bound orbits may produce periodic flares over many passages, known as repeating partial tidal disruption events (TDEs).

Relativistic cross sections of tidal disruption events

open access: yesEPJ Web of Conferences, 2012
In this contribution I introduce and discuss the so-called cross sections of tidal disruption and partial mass stripping of stars after a tidal encounter with a rotating supermassive black hole. The presented approach is fully relativistic.

Repeated Partial Disruptions in a White Dwarf–Neutron Star or White Dwarf–Black Hole Merger Modulate the Prompt Emission of Long-duration Merger-type GRBs

open access: yesThe Astrophysical Journal Letters
The progenitors of gamma-ray bursts (GRBs) have long been an unresolved issue. GRB 230307A stands out as an exceptionally bright event, belonging to the long-duration GRBs but also exhibiting a late-emission component reminiscent of a kilonova.

Exploring the Link between Extreme Coronal Line Emitters and Tidal Disruption Events

open access: yesThe Astrophysical Journal
Galaxies with minimal or no activity from their nucleus can still exhibit significant coronal line (CL) emission, often exceeding the strength of typical narrow emission lines. Many of these CLs require ionization potentials of ≥100 eV, implying the need

Ultradeep Cover: An Exotic and Jetted Tidal Disruption Event Candidate Disguised as a Gamma-Ray Burst

open access: yesThe Astrophysical Journal Letters
Gamma-ray bursts (GRBs) are traditionally classified as either short GRBs with durations ≲2 s that are powered by compact object mergers or long GRBs with durations ≳2 s that are powered by the deaths of massive stars.

Simulations of the Collision between a Debris Stream and an Outer Dusty Torus: A Possible Channel for Forming a Fast-rise and Long-delay Radio Outburst in Tidal Disruption Events

open access: yesThe Astrophysical Journal
A geometrically thick dusty torus structure is believed to exist in the nuclear regions of galaxies (especially in active galactic nuclei). The debris stream from a tidal disruption event (TDE) will possibly collide with the dusty torus and produce a ...

Stochastic tidal disruption of clusters

open access: yesThe Astrophysical Journal, 1977
We suppose that the tidal disruption of star clusters can be described by a stochastic process, and formulate the problem in terms of the theory of stochastic processes. This method has several advantages. As an example we consider a spherically symmetric cluster with uniform mean density, and calculate the rate of increase in energy of a test star to ...

Detecting Population III Stars through Tidal Disruption Events in the Era of JWST and Roman

open access: yesThe Astrophysical Journal Letters
The first-generation metal-free stars, referred to as Population III (Pop III) stars, are believed to be the first objects to form out of the pristine gas in the very early Universe.
