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.

The dynamics of head-on collisions of spherical stellar systems [PDF]

Astrophysics and Space Science, 1986
Energy changes in a head-on collision between two unequal Plummer model stellar systems (galaxies) are studied analytically under the impulsive approximation. The variation of the disruptive effects within and the mass escape from systems widely differing in mass and scalelength ratios are determined and some physical implications regarding the ...

The Effect of Multiplicity of Stellars Encounters and the Convergence of Collision Integral in the Stellar System [PDF]

International Astronomical Union Colloquium, 1993
AbstractThe multiplicity factor of stellar encounters in the infinite homogeneous layer with the constant thickness H has been studied. It is seen that simultaneous effect of Chaotically distributed distant field stars leads to the convergence of the collision integral for the great distances in the plane disk and in the layer of the constant finite ...

Collision-Induced Molecular Absorption in Stellar Atmospheres [PDF]

, 1995
Collision-induced absorption (CIA) arises in small complexes of inert atoms or molecules due to dipole moments temporarily induced during intermolecular interactions. It is well known that CIA is the major source of the infrared opacity of dense planetary atmospheres, which are composed of nonpolar molecules.

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
