Building Blue Stragglers with Stellar Collisions [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision product was completely mixed during the collision.It is known from hydrodynamical simulations of ...

Heating of stellar systems by binary collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 1983 On a utilise des resultats d'integrations numeriques de rencontres binaire-binaire aleatoires pour etudier le chauffage et la perte de masse des systemes stellaires denses par suite de collisions binaires. On en deduit une simulation des collisions binaires dans un systeme a distribution des vitesses presque maxwellienne.

Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants [PDF]
The Astrophysical Journal, 2023 Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can occur between stars before they evolve off the main sequence.

Stellar Collisions and Blue Straggler Stars in Dense Globular Clusters [PDF]
The Astrophysical Journal, 2013 Blue straggler stars (BSS) are abundantly observed in all Galactic globular clusters (GGC) where data exist. However, observations alone cannot reveal the relative importance of various formation channels or the typical formation times for this well studied population of anomalous stars.

Accretion flares from stellar collisions in galactic nuclei [PDF]
Astronomy & AstrophysicsContext. The strong tidal force in a supermassive black hole’s (SMBH) vicinity, coupled with a higher stellar density at the center of a galaxy, make it an ideal location to study the interaction between stars and black holes. Two stars moving near the SMBH could collide at a very high speed, which can result in a high energy flare.

A binary-related origin mediated by environmental conditions for blue straggler stars [PDF]
Nature CommunicationsBlue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enhancement processes, involving binary evolution or stellar collisions.

A Supernova Remnant Collision with a Stellar Wind [PDF]
The Astrophysical Journal, 2003 Numerical simulations of the interaction between supernova ejecta and a stellar wind are presented. We follow the temporal evolution of the shock fronts that are formed through such an interaction and determine the velocities, temperatures and densities.

Dynamics of Stellar Systems with Collisions: Eigenvalues and Eigenfunctions in Nearly Collisionless Limit [PDF]
The Astronomical JournalWe examine the decay of perturbations in an infinite homogeneous self-gravitating model with a Maxwellian distribution function (DF) when weak collisions are present.
