Proton/electron temperature ratio in the magnetotail
We study the temperature ratio of protons and electrons based on statistics of Cluster observations in the Earth’s magnetotail from 2001 to 2004. During these years, from June to November, the Cluster spacecraft visited the plasma sheet at the distance r ∼−19RE. We use proton and electron moments collected in the central region of the plasma sheet (|Z|< 5RE). We find an average ratio of proton ...
متن کاملIon temperature anisotropy across a magnetotail reconnection jet
A significant fraction of the energy released by magnetotail reconnection appears to go into ion heating, but this heating is generally anisotropic. We examine ARTEMIS dual-spacecraft observations of a long-duration magnetotail exhaust generated by antiparallel reconnection in conjunction with particle-in-cell simulations, showing spatial variations in the anisotropy across the outflow far (>10...
متن کاملHelicon waves in the magnetotail
[1] The helicon modes are studied in Earth’s magnetotail using the Harris sheet as a model of its equilibrium. The plasma sheet is divided into two regions: In region 1 both the electrons and the ions are treated as magnetized, whereas in region 2 the electrons are treated as magnetized but the ions are unmagnetized. The eigenmode equation for the low-frequency, parallel propagating right-hand ...
متن کاملPlasmas in the Earth ' S Magnetotail
An overview of the general characteristics of plasmas within the Earth's magnetotail and its environs is presented. Present knowledge of the plasmas within these regions as gained via in situ measurements provides the general theme, although observations of magnetic fields, energetic particles and plasma waves are included in the discussion. Primary plasma regimes in the magnetotail are the pla...
متن کاملElectron acoustic solitons in the Earth’s magnetotail
Small amplitude electron – acoustic solitons are studied in a magnetized plasma consisting of two types of electrons, namely cold electron beam and background plasma electrons and two temperature ion plasma. The analysis predicts rarefactive solitons. The model may provide a possible explanation for the perpendicular polarization of the low-frequency component of the broadband electrostatic noi...
