Glitching pulsars: unraveling the interactions of general relativity with quantum fields in the strong field regimes
A. A. Hujeirat, R. Samtaney
We present a modification of our previous model for the mechanisms underlying the glitch phenomena in pulsars and young neutron stars. Accordingly, pulsars are born with embryonic…
How massive are the superfluid cores in the Crab and Vela pulsars and why their glitch-events are accompanied with under and overshootings?
A. A. Hujeirat, R. Samtaney
The Crab and Vela are well-studied glitching pulsars and the data obtained sofar should enable us to test the reliability of models of their internal structures. Very recently it w…
Richtmyer-Meshkov Instability of an Imploding Flow with a Two-Fluid Plasma Model
Y. Li, R. Samtaney, D. Bond +1
The two-fluid (ions and electrons) plasma Richtmyer-Meshkov instability of a cylindrical light/heavy density interface is numerically investigated without an initial magnetic field…
Cross helicity sign reversals in the dissipative scales of magnetohydrodynamic turbulence
V. Titov, R. Stepanov, N. Yokoi +2
We perform direct numerical simulations of magnetohydrodynamic (MHD) turbulence with kinetic energy and cross helicity injections at large scales. We observe that the cross helicit…
Kinetic Turbulence in Astrophysical Plasmas: Waves and/or Structures?
D. Groselj, C. H. K. Chen, A. Mallet +3
The question of the relative importance of coherent structures and waves has for a long time attracted a great deal of interest in astrophysical plasma turbulence research, with a…
Magnetic reconnection and stochastic plasmoid chains in high-Lundquist-number plasmas
N. F. Loureiro, R. Samtaney, A. A. Schekochihin +1
A numerical study of magnetic reconnection in the large-Lundquist-number (), plasmoid-dominated regime is carried out for up to . The theoretical model of Uzdensky {\i…
Formation of Plasmoid Chains in Magnetic Reconnection
R. Samtaney, N. F. Loureiro, D. A. Uzdensky +2
A detailed numerical study of magnetic reconnection in resistive MHD for very large, previously inaccessible, Lundquist numbers () is reported. Large-aspect-rati…
The remnant of GW170817: a trapped neutron star with a hypermassive incompressible superfluid core
A. A. Hujeirat, R. Samtaney
Our bimetric spacetime model of glitching pulsars is applied to the remnant of GW170817. Accordingly, pulsars are born with embryonic incompressible superconducting gluon-quark sup…
