Annual Review of Astronomy and Astrophysics
Magnetic reconnection—a fundamental plasma physics process, where magnetic field lines of opposite polarity annihilate—is invoked in astrophysical plasmas as a powerful mechanism of nonthermal particle acceleration, able to explain fast-evolving, bright ...

Lifetimes of 26Al and 34Cl in an astrophysical plasma
, 1999We study here the onset of thermal equilibrium affecting the lifetimes of 26Al and 34Cl nuclei within a hot astrophysical photon gas. The 26Al isotope is of prime interest for gamma ray astronomy with the observation of its delayed (t_1\2=0.74 My) 1 ...

Numerical methods for astrophysical plasmas
Computer Physics Communications, 1986This review covers some numerical methods used for astrophysical plasmas and centers mainly on methods developed for astrophysical problems. After general remarks on DELTA multiplied by (times) B in astrophysical MHD calculations, a first-order, one-sided finite-difference formulation is derived for spherical and cylindrical geometries, respectively ...

Plasma-maser effects in plasma astrophysics
Space Science Reviews, 1986The role of a new mode coupling effect (plasma-maser) in space plasma physics is reviewed. The new maser effect, the idea that the resonant electrons with the low-frequency mode can amplify the high-frequency mode, does not require population inversion of electrons. The generation mechanisms of ULF modulated ELF emissions, auroral kilometric radiation,

Dusty plasmas have first been studied in astrophysical situations. Here, we now like to highlight a few aspects of dust in the ionosphere or in our solar system. We start with noctilucent clouds and polar mesospheric summer echoes. Then, we look into dust streams near Jupiter and Saturn and how our knowledge of dusty plasmas can be used as a ...

Introduction to plasma astrophysics
Plasma Physics and Controlled Fusion, 1999We discuss the importance of plasma physics in various areas of cosmology and astrophysics: (1) the primordial plasma spectrum, (2) the cosmic microwave background, (3) the large-scale structure of the universe, (4) reionization and the metalicity of the primordial universe, (5) the first objects, (6) the primordial magnetic field, (7) clusters of ...
