Understanding the formation of stars in galaxies is central to much of modern astrophysics.
However, a quantitative prediction of the star formation rate and the initial distribution of …

▪ Abstract Turbulence affects the structure and motions of nearly all temperature and density
regimes in the interstellar gas. This two-part review summarizes the observations, theory …

We examine the effect of weak, small-scale magnetic field structure on the rate of
reconnection in a strongly magnetized plasma. This affects the rate of reconnection by …

This paper presents a theoretical framework for understanding plasma turbulence in
astrophysical plasmas. It is motivated by observations of electromagnetic and density …

We propose a phenomenological model for incompressible magnetohydrodynamic
turbulence. We argue that nonlinear-wave interaction weakens as the energy cascade …

We derive a weak turbulence formalism for incompressible magnetohydrodynamics. Three-
wave interactions lead to a system of kinetic equations for the spectral densities of energy …

We simulate incompressible MHD turbulence using a pseudospectral code. Our major
conclusions are:(1) MHD turbulence is most conveniently described in terms of …

In 1965, Kraichnan proposed that MHD turbulence occurs as a result of collisions between
oppositely directed Alfvén wave packets. Recent work has generated some controversy over …

Magnetohydrodynamic (MHD) turbulence in the solar wind is observed to show the spectral
behavior of classical Kolmogorov fluid turbulence over an inertial subrange and departures …

We consider ion heating by turbulent Alfvén waves (AWs) and kinetic Alfvén waves (KAWs)
with wavelengths (measured perpendicular to the magnetic field) that are comparable to the …
