Neutron Star Cooling

Observation of cooling neutron stars can potentially provide information about the states of matter at supernuclear densities. We review physical properties important for cooling such as neutrino emission processes and superfluidity in the stellar interior, surface envelopes of light elements due to accretion of matter and strong surface magnetic fields. The neutrino processes include the modif...

RCW 103 – Revisiting a cooling neutron star

Recent observations of the compact source embedded within the supernova remnant RCW 103 rekindle interest in the origin of this object’s emission. We contrast several models in which neutron-star cooling powers RCW 103. Specifically, either the presence of an accreted envelope or a sufficiently intense magnetic field can account for the X-ray emission from this object. Subject headings: stars: ...

Geminga: A Cooling Superfluid Neutron Star

We compare the recent temperature estimate for Geminga with neutron star cooling models. Because of its age (∼ 3.4 × 10 yr), Geminga is in the photon cooling era. We show that its surface temperature (∼ 5.2× 10 K) can be understood by both types of neutrino cooling scenarios, i.e, slow neutrino cooling by the modified Urca process or fast neutrino cooling by the direct Urca process or by some e...

Probing clumpy stellar winds with a neutron star

Context. INTEGRAL, the European Space Agency’s γ-ray observatory, tripled the number of super-giant high-mass X-ray binaries (sgHMXB) known in the Galaxy by revealing absorbed and fast transient (SFXT) systems. Aims. In these sources, quantitative constraints on the wind clumping of the massive stars could be obtained from the study of the hard X-ray variability of the compact accreting object....

Unmasking neutron star interiors using cooling simulations

We introduce a new tool for “unmasking” the composition of neutron star (NS) interiors which is based on the fact that the state of matter at high densities determines the statistics of both NS observables, the temperature-age (TA) data as well as the mass distribution. We use modern cooling simulations to extract distributions of NS masses required to reproduce those of the yet sparse data in ...
