Observations of Cooling Neutron Stars
Observations of cooling neutron stars allow to measure photospheric radii and to constrain the equation of state of nuclear matter at high densities. In this paper we concentrate on neutron stars, which show thermal (photospheric) Xray emission and have measured distances. After a short summary of the radio pulsars falling into this category we review the observational data of the 7 radio quiet...
متن کاملWIMP annihilation and cooling of neutron stars
Since Zwicky proposed the problem of the ‘‘missing mass’’ in 1933, a lot of theoretical and experimental effort has been made in order to unveil the nature of dark matter. Today, WMAP has provided very accurate data regarding the matter density in the Universe [1]. The energy density of the Universe is composed of 4% atoms and roughly 22% dark matter. Data from recent observations indicate that...
متن کاملCooling of Neutron Stars and 3P2 Neutron Gap
We study the dependence of the cooling of isolated neutron stars on the magnitude of the 3P2 neutron gap. It is demonstrated that our “nuclear medium cooling” scenario is in favor of a suppressed value of the 3P2 neutron gap.
متن کاملTheory of cooling neutron stars versus observations
We review current state of neutron star cooling theory and discuss the prospects to constrain the equation of state, neutrino emission and superfluid properties of neutron star cores by comparing the cooling theory with observations of thermal radiation from isolated neutron stars.
متن کاملCooling of superfluid neutron stars with muons
We extend our modeling of cooling of superfluid neutron stars by including the production of muons in the core, in addition to neutrons, protons, and electrons. The results are confronted with observations of middle-aged isolated NSs. Muons have little effect on the hydrostatic structure of NSs, on the slow cooling of low-mass NSs (RX J0822–43 and PSR 1055–52 in our model) and on the rapid cool...
