51. Physics of isolated neutron stars from their X-ray emission

X-ray spectral properties of isolated neutron stars (magnetars, magnificient seven, CCOs, rotation-powered pulsars) carry precious information about the surface and inner temperature and magnetic field. An overview of the heterogeneous observational properties of the whole X-ray pulsar population is presented and used to constrain properties of the NS interior, surface and magnetosphere.

35. Statistical ages and the cooling rate of X-ray dim isolated neutron stars

Dr Ramandeep Gill (CITA (University of Toronto))

The cooling theory of neutron stars is corroborated by its comparison with observations of thermally emitting isolated neutron stars and accreting neutron stars in binary systems. An important ingredient for such an analysis is the age of the object, which, typically, is obtained from the spin-down history. This age is highly uncertain if the object's magnetic field varies appreciably over...

43. Probing the crusts of transiently accreting neutron stars

Dr Nathalie Degenaar (University of Michigan)

In transient X-ray binaries, the crust of a neutron star becomes temporarily heated during accretion outbursts, while it subsequently cools in quiescence when accretion has ceased. This crustal cooling can be observed by studying the thermal X-ray emission from quiescent neutron stars with sensitive X-ray satellites. Comparing these observations with theoretical simulations provides a unique...

127. Quiescent thermal emission of neutron stars in LMXBs

Dr Deborah Aguilera (Deutsches Zentrum fuer Luft- und Raumfahrt e.V., Bremen, Germany)

27/03/2014, 15:30

The theoretical modeling of the thermal relaxation of the neutron star crust in low mass X-ray binaries may be used to establish constraints on the crust and envelope composition and transport properties, depending on the astrophysical scenarios assumed. I will show numerical simulations of the neutron star crust thermal evolution and compare them with inferred surface temperatures for...
