Bulk viscosity of strange matter and r-modes in neutron stars
Debarati Chatterjee, Debades Bandyopadhyay
We discuss bulk viscosity due to non-leptonic processes involving hyperons and Bose-Einstein condensate of negatively charged kaons in neutron stars. It is noted that the hyperon b…
Bulk viscosity and r-modes of neutron stars
Debarati Chatterjee, Debades Bandyopadhyay
The bulk viscosity due to the non-leptonic process involving hyperons in condensed matter is discussed here. We find that the bulk viscosity is modified in a superconducting…
Role of antikaon condensation in r-mode instability
Debarati Chatterjee, Debades Bandyopadhyay
We investigate the effect of antikaon condensed matter on bulk viscosity in rotating neutron stars. We use relativistic field theoretical models to construct the equation of state…
Hyperon bulk viscosity in the presence of antikaon condensate
Debarati Chatterjee, Debades Bandyopadhyay
We investigate the hyperon bulk viscosity due to the non-leptonic process in condensed matter and its effect on the r-mode instability in neu…
Bulk viscosity in kaon condensed matter
Debarati Chatterjee, Debades Bandyopadhyay
We investigate the effect of condensed matter on bulk viscosity and r-mode instability in neutron stars. The bulk viscosity coefficient due to the non-leptonic process $n \ri…
Effect of hyperon-hyperon interaction on bulk viscosity and r-mode instability in neutron stars
Debarati Chatterjee, Debades Bandyopadhyay
We investigate the effect of hyperon matter including hyperon-hyperon interaction on bulk viscosity. Equations of state are constructed within the framework of a relativistic field…
