Binary collision losses in stellarators

Plasma Physics, 1969
There can exist a class of particles in stellarator fields for which the cancellation of the toroidal drift is incomplete. These localised particles reflected in the gradients of the helical field, can drift through the separatrix of particular stellarators no matter how strong the field; they form a loss region in velocity space.

Gas Cloud Collisions and Stellar Cluster Formation

2011
In this paper we present computer simulations of interstellar cloud collisions that for a given range of initial conditions could favor stellar cluster formation. We first construct a single spherical molecular hydrogen cloud with the Plummer radial density distribution with rigid rotation and an m = 2 density perturbation. The isolated cloud collapses

Cosmic collisions spin stellar corpses into gold

New Scientist, 2013
A smash involving two neutron stars has spat out 10 moons' worth of gold, and may explain how the universe got its stock of the precious ...

Dynamics of Dense Stellar Systems Including the Effects of Stellar Collisions

1994
Dynamical evolution of dense stellar systems is followed by integrating Fokker-Planck equation including successive mergers between stars. We have assumed that all the tidal captures lead to mergers. The initial cluster is assumed to be a single component Plummer model with mass of individual stars being 0.7 M⊙. The highest mass that is allowed to form

Stellar Collisions within Very Wide Binaries

2014
Although rare in the Milky Way, star-star collisions are predicted to occur within the dense cores of globular clusters, in evolving triple star systems, and possibly very near the Galactic center. It has recently been shown that very wide binary star systems can have their stellar orbits driven to very eccentric states by other passing field stars and
