Neutron star strain

  • The neutron star coalescence candidate is also clearly visible in data from the LIGO Livingston detector, although there is a coincident noise artifact in the L1 data. To be clear, the binary neutron star candidate is clearly visible in the L1 data on top of the noise artifact. There is no evidence for any noise artifact at H1.
Although possible, this strains our current understanding of binary and stellar evolution, arguing strongly that the maximum neutron star mass is below 2.3-2.4 M ⊙. Advanced LIGO will be able to place more stringent constraints on this merger rate, and this measured merger rate will provide more firm constraints on the maximum neutron star mass.

Apr 05, 2010 · The double neutron star inspiral range for Advanced LIGO is projected to be 300 Mpc, adequate to see several events per year even at the pessimistic end of the source estimates. There is little doubt that the new window on the universe will finally be cracked open.

Rapidly spinning neutron stars in our Galactic neighborhood are promising sources of quasi-monochromatic continuous gravitational waves observable by the current LIGO detectors. I describe a search done on the LIGO S5 data, looking for an isolated neutron star hypothesized to be at a distance of about 100 parsecs. This
  • Neutron stars, which are dense stellar remnants left behind by stellar explosions, are thought to max out at about 2.5 solar masses because any larger star is liable to crumple under its own weight.

    The maximum possible size of these mountains depends on the breaking strain of neutron star crust. With multimillion ion molecular dynamics simulations of Coulomb solids representing the crust, we show that the breaking strain of pure single crystals is very large and that impurities, defects, and grain boundaries only modestly reduce the ...

    “Mountains” in neutron stars • Any mechanism leading to a non-axisymmetric mass quadrupole is interesting for GW emission! (note: in this regard the rotational deformation is irrelevant). • The “mountain” may be “buried” in the stellar interior. Accreting neutron stars only Mechanisms for mountains Magnetic forces

    Neutron stars can act as periodic sources if their axisymmetry is broken. There are several possible mechanisms in the literature which can deform the star, e.g. thermally [2], or induce it to precess. The dipole magnetic field of an isolated neutron star induces deformations with mass ellipticity ε 10 9, too small to be detected by

    The kilohertz frequencies of QPOs from accreting neutron star systems imply that they are generated in regions of strong gravity, close to the star. This suggests that observations of the QPOs can be used to con-strain the properties of neutron stars themselves, and in particular to inform us about the properties of

If a neutron star is in a close orbit around a normal companion star, it can capture matter flowing away from that star. This captured matter will form a disk around the neutron star from which it will spiral down

LIGO data revealed that the object created by the neutron-star merger is about 2.7 times the mass of the sun. It is therefore either the lowest-mass black hole ever identified, or the most massive neutron star, the researchers said.

    On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational-wave signal, GW170817, offers a novel opportunity to directly probe the properties of matter at the extreme conditions found in the interior of these stars.

    I discuss elastic properties of neutron star crust in the framework of static Coulomb solid model when atomic nuclei are treated as non-vibrating point charges; electron screening is neglected. The results are also applicable for solidified white dwarf cores and other materials, which can be modeled as Coulomb solids (dusty plasma, trapped ions, etc.). I demonstrate that the Coulomb part of ...

May 06, 2009 · "The large breaking strain that we find should support mountains on rapidly rotating neutron stars large enough to efficiently radiate gravitational waves." Because of the intense pressure found on neutron stars, structural flaws and impurities that weaken things like rocks and steel are less likely to strain the crystals that form during the nucleosynthesis that occurs to form neutron star crust.

Abstract Neutron star (binary neutron star and neutron star–black hole) mergers are believed to produce short-duration gamma-ray bursts (GRBs). They are also believed to be the dominant source of gravitational waves to be detected by the advanced LIGO and advanced VIRGO and the dominant source of the heavy r-process elements in the universe.
