Resonant radii of kHz quasi-periodic oscillations in Keplerian discs orbiting neutron stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
Exchange of dominance between twin kHz quasi-periodic oscillations (QPOs) observed in some low-mass-X-ray-binaries (LMXB) suggests the possibility of a resonance between two oscillatory modes.
Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke (Nature, 462, 71 (2009)) that the thermal radiation of this star is well-d...
Ambipolar diffusion in superfluid neutron stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
In this paper we reconsider the problem of magnetic field diffusion in neutron star cores. We model the star as consisting of a mixture of neutrons, protons and electrons, and allow for particle react...
Generalized equation of state for cold superfluid neutron stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Mature neutron stars are expected to contain various kinds of superfluids in their interiors. Modeling such stars requires the knowledge of the mutual entrainment couplings between the different conde...
Oscillations and instabilities in neutron stars with poloidal magnetic fields
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We study the time evolution of non-axisymmetric linear perturbations of a rotating magnetised neutron star, whose magnetic field is multipolar and purely poloidal. The background stellar configuration...
Model atmospheres of X-ray bursting neutron stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/23
We present an extended set of model atmospheres and emergent spectra of X-ray bursting neutron stars in low mass X-ray binaries. Compton scattering is taken into account.
Absorption Features in Spectra of Magnetized Neutron Stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/23
The X-ray spectra of some magnetized isolated neutron stars (NSs) show absorption features with equivalent widths (EWs) of 50 - 200 eV, whose nature is not yet well known.
Internal Heating of Old Neutron Stars: Contrasting Different Mechanisms

2010/3/9
The thermal emission detected from the millisecond pulsar J0437-4715 is not explained by standard cooling models of neutron stars without a heating mechanism. We investigated three heating mechanisms ...

Relativistic Neutron Stars Shear Instability
2010/3/18
We present new results on instabilities in rapidly and differentially rotating neutron stars. We model the stars in full general relativity and describe the stellar matter adopting a cold realistic eq...

2009/5/22
Astrophysicists looking for gravitational waves should set their sights on mountainous neutron stars, according to a new numerical study by researchers in the US. The study also suggests that the crus...
