dc.description.abstract | Magnetospheric Multiscale spacecraft (MMS) mission has observed electrostatic solitary waves (ESWs) in the reconnection jet region in the Earth's magnetotail. An ion-acoustic soliton model, based on Sagdeev pseudopotential technique, is proposed to explain these ESWs. The reconnection jet plasma is modeled by a three-component magnetized plasma consisting of hot electrons and two cold ion beams streaming parallel and anti-parallel to the magnetic field, B respectively. The model predicts four types of ion-acoustic solitons, namely, two fast and two slow ion-acoustic solitons, where one of each type propagates parallel and another anti-parallel to the ambient magnetic field, respectively. The model predicts positive potential solitons with amplitudes ∼ (51-539) V, associated bipolar electric fields with amplitudes in the range of ∼ (3-69) mV m −1 , and the soliton widths of ∼ (4.5-10.3) Debye lengths. Theoretical predictions are found to be in good agreement with the observed characteristics of ESWs in the reconnection jet region by MMS mission. | en_US |
