We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

▪ 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 …

This book presents an introduction to, and modern account of, magnetohydrodynamic
(MHD) turbulence, an active field both in general turbulence theory and in various areas of …

be considered as a random variable in time with an associated probability distribution
function (pdf), a condition on the pdf for the spontaneous development of hierarchical …

We present results of large-scale three-dimensional simulations of supersonic Euler
turbulence with the piecewise parabolic method and multiple grid resolutions up to 2048 3 …

Observed molecular clouds often appear to have very low star formation efficiencies and
lifetimes an order of magnitude longer than their free-fall times. Their support is attributed to …

We present a database of 264 cores mapped in the (J, K)=(1, 1) and (2, 2) lines of NH 3. We
list the core gas properties—peak positions, total ammonia column densities, intrinsic line …

Supersonic random motions are observed in dark clouds and are traditionally interpreted as
Alfvén waves, but the possibility that these motions are super-Alfvénic has not been ruled …

The edges of molecular clouds - Fractal boundaries and density structure ADS Classic is
now deprecated. It will be completely retired in October 2019. This page will automatically …

Molecular clouds are a fundamental ingredient of galaxies: they are the channels that
transform the diffuse gas into stars. The detailed process of how they do it is not completely …
