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.

Stellar collisions in globular clusters: the origin of multiple stellar populations [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Two generations of stars, G1 and G2, typically populate Galactic globular clusters (GCs). The origin of G2 stars is unclear. We uncover two empirical dependencies between GC characteristics, which can be explained by the formation of G2 main-sequence (MS) stars due to collision/merging of their primordial counterparts (G1).

Dynamics of Stellar Collisions
, 2000 I compare gas-dynamical and stellar-dynamical models of collisions. These two models have distinctly different physics; for example, shocks introduce irreversibility in gas systems, while stellar systems evolve in a completely reversible fashion. Nonetheless, both models yield broadly similar results, suggesting that analogies between gas and stellar ...

On the stability and collisions in triple stellar systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 A significant fraction of main sequence stars are part of a triple system. We study the long-term stability and dynamical outcomes of triple stellar systems using a large number of long-term direct N-body integrations with relativistic precession. We find that the previously proposed stability criteria by Eggleton & Kiseleva 1995 and Mardling &

Stellar Collisions and Mergers in the Galactic Center
, 2000 Stars are most likely to merge or collide in regions of the highest stellar densities, and our own Galactic Center contains many stars packed into a relatively small volume -- even the ambient stellar number density in the central 50 pc is quite high, ~10^3 stars pc^{-3}.
