Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be “seen” by looking at the stars. The new model, developed in...
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...
Variable stars magnitudes estimations exploiting the eye physiology
Variable the eye physiology
2011/9/29
The physiology of the dark adaption process of the eye is revisited from an astronomical point of view. A new method for the magnitude estimation of a star is presented. It is based upon the timing of...
Energy release from hadron-quark phase transition in neutron stars and the axial $w$-mode of gravitational waves

Describing the hyperonic and quark phases of neutron stars with an isospin- and momentum-

Holographically smeared Fermi surface: Quantum oscillations and Luttinger count in electron stars
Holographically smeared Fermi surface Quantum oscillations
2010/12/23
We apply a small magnetic field to strongly interacting matter with a gravity dual description as an electron star. These systems are both metallic and quantum critical at low energies. The resulting ...
The spin parameter of uniformly rotating compact stars
spin parameter of uniformly compact stars
2010/12/21
We study the dimensionless spin parameter j (= cJ/(GM2)) of uniformly rotating neutron stars
and quark stars in general relativity. We show numerically that the maximum value of the spin
parameter o...
Tkachenko modes in rotating neutron stars: the effect of compressibility and implications for pulsar timing noise
Tkachenko modes rotating neutron stars effect of compressibility implications pulsar timing noise
2010/12/21
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...
Stationary, Axisymmetric Neutron Stars with Meridional Circulation in General Relativity
Stationary Axisymmetric Neutron Stars Meridional Circulation General Relativity
2010/12/20
We present the first stationary, axisymmetric neutron star models with meridional circulation in general relativity. For that purpose, we developed GRNS, a new code based on a fixed point iteration.
Further Argument Against the Motion of the Earth, Based on Telescopic Observations of the Stars: An English Rendition of Chapter 30, Book 9, Section 4, Pages 460-463 of the Almagestum Novum Volume II of G. B. Riccioli
Further Argument Against Physics
2010/11/16
The Italian Jesuit astronomer Giovanni Battista (Giambattista) Riccioli constructed a powerful, thoroughly scientific argument in favor of geocentrism - an argument based on telescopic observations o...
Gravitational Waves from the $r$-mode instability of neutron stars: effect of magnetic field
Gravitational Waves $r$-mode instability neutron stars: effect magnetic field
2010/12/20
Studies have shown that emission of gravitational waves drives an instability in the r-modes
of young rapidly rotating neutron stars carrying away most of the angular momentum through

Relativistic redshift effects and the Galactic-center stars
Relativistic redshift Galactic-center stars
2010/3/17
The high pericenter velocities (up to a few percent of light) of the S stars around the Galactic-center black hole suggest that general relativistic effects may be detectable through the time variatio...
