Strangeness in Astrophysics and Cosmology
Tillmann Boeckel, Matthias Hempel, Irina Sagert +3
Some recent developments concerning the role of strange quark matter for astrophysical systems and the QCD phase transition in the early universe are addressed. Causality constrain…
Dissipation of radial oscillations in compact stars
Basil A. Sa'd, Jürgen Schaffner-Bielich
We demonstrate that there exists a new mechanism for dissipating the energy of stellar oscillations. For neutron stars, in particular, we show that the mechanical energy of density…
Mutual friction in a cold color flavor locked superfluid and r-mode instabilities in compact stars
Massimo Mannarelli, Cristina Manuel, Basil A. Sa'd
Dissipative processes acting in rotating neutron stars are essential in preventing the growth of the r-mode instability. We estimate the damping time of r-modes of an hypothetical…
Quark contribution to r-mode instabilities for several phases of deconfined quark matter
Basil A. Sa'd
R-mode instabilities lead to specific signatures in the evolution of rotating pulsars, and may provide a unique signature which can identify the phase of matter that exists in the…
Bulk viscosity of strange quark matter: Urca versus non-leptonic processes
Basil A. Sa'd, Igor A. Shovkovy, Dirk H. Rischke
A general formalism for calculating the bulk viscosity of strange quark matter is developed. Contrary to the common belief that the non-leptonic processes alone give the dominant c…
Bulk viscosity of spin-one color superconductors with two quark flavors
Basil A. Sa'd, Igor A. Shovkovy, Dirk H. Rischke
We consider the contribution of the Urca-type processes to the bulk viscosity of several spin-one color-superconducting phases of dense two-flavor quark matter. In the so-called tr…
