P.; Winske, Dan Abstract: Wave-particle transport in a collisionless plasma is due to particle scattering by enhanced fluctuations associated with the growth of instabilities. In particular, relatively short wave-length kinetic instabilities are ... NASA Center: NASA (non Center Specific) Publication Year: 1992 Added to NTRS: 2004-11-03 Accession Number: 92A28097; Document ID: 19920045473 Hybrid Modeling of the Formation and Structure of Thin Current Sheets in the Magnetotail Author(s): Hesse, M.; Winske, Dan; Birn, Joschim Abstract: Hybrid simulations are used to investigate the formation of a thin current sheet inside the plasma sheet of a magnetotail-like configuration. The initial equilibrium is subjected to a driving electric field qualitatively ... NASA Center: Goddard Space Flight Center Publication Year: 1996 Added to NTRS: 2004-11-03 Accession Number: 97N11213; Document ID: 19970001396; Report Number: CONF-9605109-2, DE96-012826, LA-UR-96-2306 The proton cyclotron instability and the anisotropy/B inverse correlation Author(s): Gary, S. Peter; Mckean, Michael E.; Winske, Dan; Anderson, Brian J.; Denton, Richard E.; Fuselier, Stephen A. Abstract: Spacecraft observations in the strongly compressed subsolar magnetosheath show an inverse correlation between the proton temperature anistrophy (T(sub perpendicular to p)/T(sub parallel to p) greater than 1 where ... NASA Center: Goddard Space Flight Center Publication Year: 1994 Added to NTRS: 2004-11-03 Accession Number: 95A61148; Document ID: 19950029549 Hot proton anisotropies and cool proton temperatures in the outer magnetosphere Author(s): Gary, S. Peter; Moldwin, Mark B.; Thomsen, Michelle F.; Winske, Dan; Mccomas, David J. Abstract: The hot protons of the outer magnetosphere typically exhibit a temperature anistropy such that T(sub perp)/T(sub parallel) greater than 1, where perpendicular and parallel symbols denote directions relative to the background ...

Peter; Madland, Christian D.; Winske, Dan; Omidi, Nojan Abstract: This paper presents a one-dimensional electromagnetic hybrid computer simulation of distant cometary environments, in which protons and oxygen ions are injected continuously at the same time. It is demonstrated that, when, ...
