Tidal Disruption of Protoclusters in Giant Molecular Clouds

, 2008
We study the collapse of protoclusters within a giant molecular cloud (GMC) to determine the conditions under which collapse is significantly disrupted.

Pre-peak Emission in Tidal Disruption Events

The Astrophysical Journal
The rising part of a tidal disruption event light curve provides unique insight into early emission and the onset of accretion. Various mechanisms are proposed to explain the pre-peak emission, including shocks from debris interaction and reprocessing of

Hydrodynamical Simulations to Determine the Feeding Rate of Black Holes by the Tidal Disruption of Stars: The Importance of the Impact Parameter and Stellar Structure

, 2015
The disruption of stars by supermassive black holes has been linked to more than a dozen flares in the cores of galaxies out to redshift $z \sim 0.4$. Modeling these flares properly requires a prediction of the rate of mass return to the black hole after

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick

The Astrophysical Journal Letters
The surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Hyper Velocity Stars and the Restricted Parabolic 3-body Problem

, 2009
Motivated by detections of hypervelocity stars that may originate from the Galactic Center, we revist the problem of a binary disruption by a passage near a much more massive point mass.

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

The 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

EPJ 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.

Signatures of LCDM substructure in tidal debris

, 2008
In the past decade, surveys of the stellar component of the Galaxy have revealed a number of streams from tidally disrupted dwarf galaxies and globular clusters.

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

The 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.
