Planetary plasma and magnetic field environments can be studied by in situ measurements or by remote sensing. While the former provide precise information about plasma behaviour, instabilities and dyn...
Varying disc-magnetosphere coupling as the origin of pulse profile variability in SAX J1808.4-3658
accretion accretion discs – pulsars:individual:SAX J1808.4–3658 – stars:neu-tron – X-rays:binaries
2011/9/26
Accreting millisecond pulsars show significant variability of their pulse profiles, especially at low accretion rates. On the other hand, their X-ray spectra are remarkably similar with not much varia...
Formation of "Lightnings" in a Neutron Star Magnetosphere and the Nature of RRATs
neutron stars, pulsars, rotating radio transients.
2011/9/15
The connection between the radio emission from “lightnings” produced by the absorption of high-energy photons from the cosmic gamma-ray background in a neutron star magnetosphere and radio bursts from...

Anomalous Conductivities Frictional Heating
2017/3/22
Global magnetospheric MHD codes using ionospheric conductances based on laminar
models systematically overestimate the cross-polar cap potential during storm time by
up to a factor of two. At these ...
Conjectured chaotic nature of the ionosphere-magnetosphere coupling in a reconfigurating magnetosphere
Conjectured chaotic nature ionosphere-magnetosphere coupling reconfigurating magnetosphere
2009/11/16
During substorms the magnetic field configuration changes in time; stretching of the magnetosphere during growth phase is followed by its collapse after the onset of the expansion phase. In this study...
Evaluation on the analogy between the dynamic magnetosphere and a forced and/or self-organized critical system
Evaluation on the analogy dynamic magnetosphere self-organized critical system
2009/11/12
The dissipation power and size of auroral blobs are investigated in detail to examine the possible analogy between the dynamic magnetosphere and a forced and/or self-organized critical system. The dis...
