8. Generation of X-rays from Comet C/Hyakutake 1996 B2

Abstract

The instability resulting from the relative motion of newly picked-up cometary photoions and the solar wind generates lower hybrid waves that are capable of accelerating electrons to the keV range of energies. These electrons may be responsible for the x-rays from comet C/Hyakutake 1996 B2 seen by the Rontgen X-ray Satellite. The inferred x-ray photon power depends on the electron energy, with keV electrons providing values of photon power two orders of magnitude greater than 100 eV electrons. These observations and in particular, spectral resolution of the x-rays, should provide more insight into the composition of the comet., Observations by the Rontgen X-ray Satellite (ROSAT) on 26 to 28 March 1996 of x-ray emission from comet C/Hyakutake 1996 b2 (1) appear to have been a surprise to most [...]

17. Alfven soliton created by Reynolds' stress of the lower-hybrid waves

Author

Üçer, D. and Shapiro, V.D.

Subjects
*MAGNETOHYDRODYNAMIC waves, *DENSITY, *NONLINEAR statistical models, *IONOSPHERE
Abstract

The modulational interaction of very short wavelength lower-hybrid waves with slow density modulations associated with inertial Alfven mode is investigated. Nonlinear equations governing this interaction are derived and soliton-like solutions of these equations are discussed in the context of auroral ionosphere. [Copyright &y& Elsevier]

Subjects
*ENERGY dissipation, *ION acoustic waves, *OSCILLATIONS
Abstract

Describes numerical solutions of Zakharov-type equations for lower-hybrid (LH) waves, including pumping at the long wavelengths and dissipation at short wavelengths in the form of dissipative cavitons. Quasistationary structure undergoing many sequences of collapse due to dissipation; Ion-wave interactions; Possibility of trapping of short-wavelength LH oscillations.

19. Analytical model of the 'tilting' instability.

Author

Rosenbluth, M.N. and Shapiro, V.D.

Subjects
*CASCADES (Fluid dynamics), *FLUID dynamics
Abstract

Proposes an analytical model of the tilting instability that exhibits inverse cascade phenomenon, conserving both energy and enstrophy. View that tilting instability is an instability of convective motions two-dimensional ideal fluid transforming convection into sheared flow; Evolution of the nonlinear stage in which initial fluid convection is transformed completely into the large-scale flow.
