Hall equilibrium of thin Keplerian disks embedded in mixed poloidal and toroidal magnetic fields
Yuri M. Shtemler, Michael Mond, Gunther Rudiger
Axisymmetric steady-state weakly ionized Hall-MHD Keplerian thin disks are investigated by using asymptotic expansions in the small disk aspect ratio ε. The model incorporates the…
Mean-field dynamos in random Arnold-Beltrami-Childress and Roberts flows
N. Kleeorin, I. Rogachevskii, D. Sokoloff +1
We study magnetic field evolution in flows with fluctuating in time governing parameters in electrically conducting fluid. We use a standard mean-field approach to derive equations…
A Universal Central Engine Hypothesis for Short and Long GRBs
David Eichler, Dafne Guetta, Hadar Manis
It is noted that X-ray tails (XRTs) of short, hard -ray bursts (SHBs) are similar to X-ray flashes (XRFs). We suggest a universal central engine hypothesis, as a way of accounti…
Spectral Lags Explained as Scattering from Accelerated Scatterers
David Eichler, Hadar Manis
A quantitative theory of spectral lags for -ray bursts (GRBs) is given. The underlying hypothesis is that GRB subpulses are photons that are scattered into our line of sight by…
Evolution of initially localized perturbations in stratified ionized disks
Edward Liverts, Michael Mond
A detailed solution of an initial value problem of a vertically localized initial perturbation in rotating magnetized vertically stratified disk is presented. The appropriate linea…
Numerical experiments on dynamo action in sheared and rotating turbulence
T. A. Yousef, T. Heinemann, F. Rincon +5
Numerical simulations of forced turbulence in elongated shearing boxes are carried out to demonstrate that a nonhelical turbulence in conjunction with a linear shear can give rise…
Nonhelical mean-field dynamos in a sheared turbulence
I. Rogachevskii, N. Kleeorin
Mechanisms of nonhelical large-scale dynamos (shear-current dynamo and effect of homogeneous kinetic helicity fluctuations with zero mean) in a homogeneous turbulence with large-sc…
Current-driven instabilities in weakly ionized disks
Edward Liverts, Michael Mond, Vadim Urpin
Cool weakly ionized gaseous rotating disk form the basis for many models in astrophysics objects. Instabilities against perturbations in such disks play an important role in the th…
Particle acceleration in the driven relativistic reconnection
Yuri Lyubarsky, Michael Liverts
We study the compression driven magnetic reconnection in the relativistic electron-positron plasma. Making use of a 2.5D particle-in-cell code, we simulated compression of a magnet…
A simple determination of some characteristics of the beta Pictoris system
V. Celebonovic
The aim of this contribution is to determine the lower limit of the electron number density,the Debye temperature and the specific heat of solid grains present in the protoplanetar…
Induced scattering of short radio pulses
Yuri Lyubarsky
Effect of the induced Compton and Raman scattering on short, bright radio pulses is investigated. It is shown that when a single pulse propagates through the scattering medium, the…
The Tayler instability and the Hall effect in protoneutron stars
Guenther Ruediger, Manfred Schultz, Michael Mond +1
Collapse calculations indicate that the hot newly born protoneutron stars (PNS) rotate differentially so that strong toroidal magnetic field components should exist in the outer cr…
Mean-field dynamo in a turbulence with shear and kinetic helicity fluctuations
N. Kleeorin, I. Rogachevskii
We study effects of kinetic helicity fluctuations in a turbulence with large-scale shear using two different approaches: the spectral tau-approximation and the second order correla…
Magnetic fluctuations and formation of large-scale inhomogeneous magnetic structures in a turbulent convection
I. Rogachevskii, N. Kleeorin
Magnetic fluctuations generated by a tangling of the mean magnetic field by velocity fluctuations are studied in a developed turbulent convection with large magnetic Reynolds numbe…
New mechanism of generation of large-scale magnetic field in a sheared turbulent plasma
N. Kleeorin, I. Rogachevskii
A review of recent studies on a new mechanism of generation of large-scale magnetic field in a sheared turbulent plasma is presented. This mechanism is associated with the shear-cu…
Generation of Magnetic Field by Combined Action of Turbulence and Shear
T. A. Yousef, T. Heinemann, A. A. Schekochihin +5
The feasibility of a mean-field dynamo in nonhelical turbulence with superimposed linear shear is studied numerically in elongated shearing boxes. Exponential growth of magnetic fi…
Evolutionary Catastrophes and the Goldilocks Problem
Milan M. Cirkovic
One of the mainstays of the controversial "rare Earth" hypothesis is the "Goldilocks problem" regarding various parameters describing a habitable planet, partially involving the ro…
Efficient electron heating in relativistic shocks and gamma ray burst afterglow
M. Gedalin, M. A. Balikhin, D. Eichler
Electrons in shocks are efficiently energized due to the cross-shock potential, which develops because of differential deflection of electrons and ions by the magnetic field in the…
A Model for Fast Rising, Slowly Decaying Subpulses in Gamma-Ray Bursts
David Eichler, Hadar Manis
Gamma ray bursts (GRB's) often feature subpulses that have a distinctively asymmetric profile -- they rise quickly and decay much more slowly, while their spectrum softens slightly…
Magnetic reconnection at the termination shock in a striped pulsar wind
Jerome Petri, Yuri Lyubarsky
Most of the rotational luminosity of a pulsar is carried away by a relativistic magnetised wind in which the matter energy flux is negligible compared to the Poynting flux. Near th…
Foam-like structure of the Universe
A. A. Kirillov, D. Turaev
On the quantum stage spacetime had the foam-like structure. When the Universe cools, the foam structure tempers and does not disappear. We show that effects caused by the foamed st…

A. N. Timokhin, D. Eichler, Yu. Lyubarsky
A model is presented for the quasiperiodic component of magnetar emission during the tail phase of giant flares. The model invokes modulation of the particle number density in the…
