Explaining radio emission of magnetars via rotating and oscillating magnetospheres of neutron stars
MHD: pulsars — general — relativity — oscillations — magnetar — stars:neutron — death line — plasma magnetosphere
2011/10/10
We investigate the conditions for radio emission in rotating and oscillating magnetars, by focusing on the main physical processes determining the position of their death-lines in the P-\dot{P} diagra...
The optical/UV excess of isolated neutron stars in the RCS model
pulsars: individual RX J1308.6+2127 stars:neutron
2011/9/28
The X-ray dim isolated neutron stars (XDINSs) are peculiar pulsar-like objects, characterized by their very well Planck-like spectrum. In studying their spectral energy distributions, the optical/UV e...
Nonradial superfluid modes in oscillating neutron stars
stars: neutron – stars: oscillations – stars: interiors
2011/10/12
For the first time nonradial oscillations of superfluid nonrotating stars are self-consistently studied at finite stellar temperatures. We apply a realistic equation of state and realistic density dep...
Upper limits on the observational effects of nuclear pasta in neutron stars
relativity – gravitational waves – dense matter – stars neutron – stars
2011/7/21
The effects of the existence of exotic nuclear shapes at the bottom of the neutron star inner crust - nuclear `pasta' - on observational phenomena are estimated by comparing the limiting cases that th...
QHD equation of state for strongly magnetized neutron stars
QHD equation strongly magnetized neutron stars
2011/7/21
We investigate the quantum hadrodynamic equation of state for neutron stars (with and without including hyperons) in the presence of strong magnetic fields.
Oscillations of hot, young neutron stars: Gravitational wave frequencies and damping times
Oscillations of hot young neutron stars
2011/7/21
We study how the frequencies and damping times of oscillations of a newly born, hot proto-neutron star depend on the physical quantities which characterize the star quasi-stationary evolution which fo...
The cluster structure of the inner crust of neutron stars in the Hartree-Fock-Bogoliubov approach
cluster structure inner crust neutron stars approach
2011/10/17
We analyse how the structure of the inner curst is influenced by the pairing correlations. The inner-crust matter, formed by nuclear clusters immersed in a superfluid neutron gas and ultra-relativisti...
New eigen-mode of spin oscillations in the triplet superfluid condensate in neutron stars
Neutron star Superfl uidity Spin waves
2011/10/14
The eigen mode of spin oscillations with $\omega\simeq \sqrt{58/35}\Delta$ is predicted to exist besides already known spin waves with $\omega \simeq\Delta /\sqrt{5}$ in the triplet superfluid neutron...
Initial data for binary neutron stars with arbitrary spins
Initial data binary neutron stars arbitrary spins
2011/10/18
In general neutron stars in binaries are spinning. Due to the existence of millisecond pulsars we know that these spins can be substantial. We argue that spins with periods on the order a few dozen mi...
Towards Quark Deconfinement in Neutron Stars via Spindown: Gravitational Waves or Magnetic Braking?
Quark Deconfinement Neutron Stars Gravitational Waves Magnetic Braking
2011/9/28
A phase of interacting quark matter can arise inside the dense core of isolated neutron stars when they have been sufficiently spun down from their initial rapidly rotating configuration. In this work...
Tidal deformations of neutron stars: The role of stratification and elasticity
Tidal deformations stars:stratification elasticity
2011/9/27
We discuss the response of neutron stars to the tidal interaction in a compact binary system, as encoded in the Love number associated with the induced deformation. This problem is of interest for gra...
Energy release from hadron-quark phase transition in neutron stars and the axial $w$-mode of gravitational waves
Energy release hadron-quark phase transition axial $w$-mode of gravitational waves
2010/12/21
Describing the hyperonic and quark phases of neutron stars with an isospin- and momentum-
dependent effective interaction for the baryon octet and the MIT bag model, respectively, and using the Gibbs...
Pasta Structures of Quark-Hadron Phase Transition in Proto-Neutron Stars
Pasta Structures Quark-Hadron Phase Transition
2011/1/11
We study the quark-hadron mixed phase in proto-neutron stars with the finite-size effects. In the calculations of pasta structures appeared in the mixed phase, the Gibbs conditions require the pressur...
The Moving Hotspots model for kHz QPOs in accreting neutron stars
QPO plasma LMXB accretion
2010/11/9
3D MHD simulation of accretion onto neutron stars have shown in the last few years that
the footprint (hotspot) of the accretion flow changes with time. Two different kinds of accretion,namely the fu...
Tkachenko modes in rotating neutron stars: the effect of compressibility and implications for pulsar timing noise
Tkachenko modes rotating neutron stars compressibility pulsar timing noise
2010/11/11
Long wavelength oscillations (Tkachenko waves) of the triangular lattice of quantized vortices in super uid neutron stars have been suggested as one of the possible explanations for the timing noise o...
