Non-Maxwellian Ion Distribution in the Equatorial and Auroral Electrojets
Rattanakorn Koontaweepunya, Yakov S. Dimant, Meers M. Oppenheim
Strong electric fields in the auroral and equatorial electrojets can distort the background ion distribution function away from Maxwellian. We developed a collisional plasma kineti…
Unified fluid-model theory of instabilities in low-ionized collisional plasmas with arbitrarily magnetized multi-species ions
Y. S. Dimant, M. M Oppenheim, S. Evans +1
This paper develops a unified linear theory of local cross-field plasma instabilities, such as the Farley-Buneman, electron thermal, and ion thermal instabilities, in collisional p…
Formation of plasma around a small meteoroid: 2. Implications for radar head echo
Y. S. Dimant, M. M. Oppenheim
This paper calculates the spatial distribution of the plasma responsible for radar head echoes by applying the kinetic theory developed in the companion paper (Dimant and Oppenheim…
Formation of plasma around a small meteoroid: 1. Kinetic theory
Y. S. Dimant, M. M. Oppenheim
Every second millions of small meteoroids enter the Earth's atmosphere producing dense plasmas. Radars easily detect these plasmas and researchers use this data to characterize bot…
Generation of Electrojets in Weakly Ionized Plasmas through a Collisional Dynamo
Yakov S. Dimant, Meers M. Oppenheim, Alex. C. Fletcher
Intense electric currents called electrojets occur in weakly ionized magnetized plasmas. An example occurs in the Earth's ionosphere near the magnetic equator where neutral winds d…
Meteor generated plasma columns in E-region ionosphere: fields and diffusion
Y. S. Dimant, M. M. Oppenheim
A meteoroid penetrating the Earth's atmosphere leaves behind a trail of dense plasma in the E-region ionosphere, a region where electrons are strongly magnetized while ions are dem…
