In situ electron density profiles obtained from Arase in the night magnetic local time (MLT) sector and RBSP-B covering all MLTs are used to study small-scale irregularities present plasmasphere near plasmapause. Electron perturbations with amplitudes >10% background time-scales less than 30-min investigated here as irregularities. The statistical survey of is carried out using nearly 2 years d...

The results of large-scale, particle-in-cell simulations are presented on the role of Hall electric and magnetic fields on the structure of the electron dissipation region and outflow exhaust during the collisionless magnetic reconnection of antiparallel fields. The simulations reveal that the whistler wave plays the key role in driving the electrons away from the magnetic x-line. Further downs...

Effect of cold electron beam for Whistler mode waves have been studied for relativistic and non-relativistic subtracted biMaxwellian distribution in the presence of perpendicular AC electric field to magnetic field by using the method of characteristic solutions and kinetic approach. The detailed derivation and calculations has been done for dispersion relation and growth rate for magnetosphere...
