Abstract We derive the bulk viscous damping timescale of hybrid stars, neutron stars with quark matter core. The r -mode instability windows of the stars show that the theoretical results are consistent with the rapid rotation pulsar data, which may give an indication for the existence of quark matter in the interior of neutron stars. Hybrid stars instead of neutron or strange stars may lead to submillisecond pulsars.

Thermal Evolution of Strange Stars
We have investigated the thermal evolution of rotating strange stars with the deconfinement heating due to magnetic braking. We consider stars consisting of either normal quark matter or aExpand
The formation of submillisecond pulsars and the possibility of detection
Pulsars have been recognized to be normal neutron stars, but sometimes have been argued to be quark stars. Submillisecond pulsars, if detected, would play an essential and important role inExpand
Viscous damping of r-mode oscillations in compact stars with quark matter.
We determine characteristic time scales for the viscous damping of r-mode oscillations in rapidly rotating compact stars that contain quark matter. We present results for the color-flavor-lockedExpand
1122 Hz rotation of XTE J1739-285 as a probe of quark matter in the interior of the neutron star
The recent discovery of burst oscillation at 1122Hz in the X-ray transient XTE J1739-285 supports the suggestion that it contains a submillisecond pulsar. In our estimations of the enormousExpand

TLDR
The bulk viscosity of strange quark matter is calculated in the light of new rate expressions for the reaction u+s ↔ d+u, implying rapid damping of stellar vibrations and suppression of nonaxisymmetric instabilities for rapidly spinning pulsars. Expand
HOW TO IDENTIFY A STRANGE STAR
Contrary to young neutron stars, young strange stars are not subject to the r-mode instability which slows rapidly rotating, hot neutron stars to rotation periods near 10 ms via gravitational waveExpand
THE R-MODE INSTABILITY IN ROTATING NEUTRON STARS
In this review we summarize the current understanding of the gravitational-wave driven instability associated with the so-called r-modes in rotating neutron stars. We discuss the nature of theExpand
The Critical Rotation of Strange Stars and Rapidly Rotating Pulsars
We utilize the bulk viscosity of interacting strange quark matter to reevaluate the damping timescale. The presence of a medium effect of bulk viscosity leads to a stronger damping of r-modes, whichExpand
Effect of hyperon bulk viscosity on neutron-star r-modes
Neutron stars are expected to contain a significant number of hyperons in addition to protons and neutrons in the highest density portions of their cores. Following the work of Jones, we calculateExpand
