Orbital eccentricity of binary radio pulsars in globular clusters and the interaction between stars.

BAGCHI M. and RAY A.

Abstract (from CDS):

We analyze the observed distribution of the orbital eccentricity and period of binary radio pulsars in globular clusters using computational tools to simulate binary-single-star interactions. Globular clusters have different groups of pulsars arising from separate interaction scenarios. Intermediate eccentricities of cluster pulsars can mostly be accounted for by fly-bys although locally lower stellar densities at pulsar positions may alter the situation. Very high eccentricities are likely to be the result of exchanges and/or mergers of single stars with the binary companion of the pulsar.
