Convective Amplification of Electromagnetic Ion Cyclotron Waves From Ring-distribution Protons in the Inner Magnetosphere

Autor: Mithaiwala, Manish, Crabtree, Chris, Ganguli, Gurudas, Rudakov, Leonid, Keika, Kunihiro

The growth of electromagnetic ion cyclotron waves (EMIC) due to a ring distribution of Hydrogen ions is examined. Though these distributions are more commonly implicated in the generation of equatorial noise, their potential for exciting EMIC waves i

Analysis of Winske-Daughton 3D Electromagnetic Particle Simulation of Ion Ring Generated Lower Hybrid Turbulence

Autor: Rudakov, Leonid, Crabtree, Chris, Mithaiwala, Manish, Ganguli, Gurudas

Using electromagnetic particle-in-cell simulations Winske and Daughton [Phys Plasmas, 19, 072109, 2012] have recently demonstrated that the nonlinear evolution of a wave turbulence initiated by cold ion ring beam is vastly different in three dimensio

Co-existence of Whistler Waves with Kinetic Alfven Wave Turbulence for the High-beta Solar Wind Plasma

Autor: Mithaiwala, Manish, Rudakov, Leonid, Crabtree, Chris, Ganguli, Gurudas

It is shown that the dispersion relation for whistler waves is identical for a high or low beta plasma. Furthermore in the high-beta solar wind plasma whistler waves meet the Landau resonance with electrons for velocities less than the thermal speed,

A Concept For Elimination Of Small Orbital Debris

Autor: Ganguli, Gurudas, Crabtree, Christopher, Rudakov, Leonid, Chappie, Scott

A concept for forced reentry of small orbital debris with characteristic dimension ~ 10 cm from the highly populated sun synchronous orbit by injecting micron scale dust grains to artificially enhance drag is discussed. The drag enhancement is most e

Linear and Non-Linear Landau Resonance of Kinetic Alfv\'en Waves: Consequences for Electron Distribution and Wave Spectrum in the Solar Wind

Autor: Rudakov, Leonid, Mithaiwala, Manish, Ganguli, Gurudas, Crabtree, Chris

Kinetic Alfven wave turbulence in solar wind is considered and it is shown that non-Maxwellian electron distribution function has a significant effect on the dynamics of the solar wind plasmas. Linear Landau damping leads to the formation of a platea
