Ion acceleration at dipolarization fronts in the inner magnetosphere

open access: yes, 2017
During geomagnetic storms plasma pressure in the inner magnetosphere is controlled by energetic ions of tens to hundreds of keV. Plasma pressure is the source of global storm time currents, which control the distribution of magnetic field and couple the ...

ELECTRODYNAMICS OF AXISYMMETRIC PULSAR MAGNETOSPHERE WITH ELECTRON–POSITRON DISCHARGE: A NUMERICAL EXPERIMENT [PDF]

open access: yes, 2014
We present the first self-consistent global simulations of pulsar magnetospheres with operating e± discharge. We focus on the simple configuration of an aligned or anti-aligned rotator.

Exploration of the use of short‐wave infrared radiances in weather forecasts model Part II: Data assimilation and forecast impact assessment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.

Dissipative Pulsar Magnetosphere

open access: yes, 2008
Dissipative axisymmetric pulsar magnetosphere is calculated by a direct numerical simulation of the Strong-Field Electrodynamics equations. The magnetic separatrix disappears, it is replaced by a region of enhanced dissipation.

MHD simulations of accretion onto a dipolar magnetosphere. II. Magnetospheric ejections and stellar spin-down [PDF]

open access: yes, 2012
This paper examines the outflows associated with the interaction of a stellar magnetosphere with an accretion disk. In particular, we investigate the magnetospheric ejections (MEs) due to the expansion and reconnection of the field lines connecting the ...

Intensification of the Electron Zebra Stripes in the Earth's Inner Magnetosphere During Geomagnetic Storms

open access: yesGeophysical Research Letters
We examined rapid variations in the electron zebra stripe patterns, specifically at L = 1.5, over a three‐month duration, using twin Van Allen Probes within Earth's inner magnetosphere. During geomagnetically quiet intervals, these stripes exhibit a peak‐

Main statistical properties of hectometric continuum radiation in near-Earth space

open access: yesSolar-Terrestrial Physics, 2023
In this work, we have studied the recently discovered hectometric continuum radiation in near-Earth plasma. We have carried out a detailed statistical analysis of the occurrence of a hectometric continuum near Earth at distances 1.1–2 Re, where Re is the

Orbital modulation of emission of the binary pulsar J0737-3039B

open access: yes, 2005
In binary radio pulsar system J0737-3039, slow pulsar B shows orbital modulations of intensity, being especially bright at two short orbital phases. We propose that these modulations are due to distortion of pulsar B magnetosphere by pulsar A wind which ...

AB INITIO PULSAR MAGNETOSPHERE: THREE-DIMENSIONAL PARTICLE-IN-CELL SIMULATIONS OF OBLIQUE PULSARS [PDF]

open access: yes, 2014
We present “first-principles” relativistic particle-in-cell simulations of the oblique pulsar magnetosphere with pair formation. The magnetosphere starts to form with particles extracted from the surface of the neutron star.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

open access: yesExperimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.
