Evolution of stellar collision products in open clusters : I. Blue stragglers in N-body models of M 67 [PDF]
, 2008 Stellar collisions are an important formation channel for blue straggler stars in globular and old open clusters. Hydrodynamical simulations have shown that the remnants of such collisions are out of thermal equilibrium, are not strongly mixed and can ...

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).

Simulations of Stellar Collisions Involving Pre-Main Sequence Stars [PDF]
, 2005 In this paper, we present the results of smoothed particle hydrodynamic (SPH) simulations of collisions between pre-main sequence stars and a variety of other kinds of stars. Simulations over a range of impact parameters and velocities were performed. We

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 ...

Multiple Populations in Globular Clusters: The Possible Contributions of Stellar Collisions [PDF]
, 2010 Globular clusters were thought to be simple stellar populations, but recent photometric and spectroscopic evidence suggests that the clusters' early formation history was more complicated.

Simulations of the formation of stellar discs in the Galactic centre via cloud-cloud collisions [PDF]
, 2009 Young massive stars in the central parsec of our Galaxy are best explained by star formation within at least one, and possibly two, massive self-gravitating gaseous discs.

Evolution of stellar collision products in open clusters [PDF]
Astronomy & Astrophysics, 2008 In a companion paper we studied the detailed evolution of stellar collision products that occurred in an $N$-body simulation of the old open cluster M67 and compared our detailed models to simple prescriptions. In this paper we extend this work by studying the evolution of the collision products in open clusters as a function of mass and age of the ...
