11th Marcel Grossmann Meeting

Eleventh Marcel Grossmann Meeting on General Relativity at the Freie Universität of Berlin: July 23 - 29, 2006

Parallel Session APT5

Thermal Behaviour


Compact Stars

Modelling of the thermal behavior of compact stars (either neutron, in their many possible forms, or strange stars) is a very powerfull tool to study the nature of matter at supra-nuclear densities. This session will focus on two complementary approaches to this problem: isolated cooling compact stars and accreting ones.  Review talks will present critical observational data and the essential theory.

Some compact stars in LMXBs (Low-Mass X-ray Binaries) may be much heavier than isolated ones and together they allow to study an extended range of masses. Transiently accreting systems make it possible to study the short-time thermal response of the star while superbursting systems directly probe the interior physical conditions. Moreover, recent observations seriously challenge our standard view of neutron stars.

The later merging of the compact star and its companion (probably a white dwarf for descendants of LMXBs) is a possible central engine for short gamma-ray bursts and certainly a strong source of gravitational waves.
