We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Understanding the dominant brown dwarf and giant planet formation processes, and finding
out whether these processes rely on completely different mechanisms or share common …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

We present and discuss the results of the Herschel Gould Belt survey (HGBS) observations
in an~ 11 deg 2 area of the Aquila molecular cloud complex at d~ 260 pc, imaged with the …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

We present first results from the Herschel Gould Belt survey for the B211/L1495 region in the
Taurus molecular cloud. Thanks to their high sensitivity and dynamic range, the Herschel …

We summarize the first results from the Gould Belt Survey, obtained toward the Aquila rift
and Polaris Flare regions during the science demonstration phase of Herschel. Our 70–500 …

Context. Molecular filaments have received special attention recently thanks to new
observational results on their properties. In particular, our early analysis of filament …

We provide a first look at the results of the Herschel Gould Belt survey toward the IC 5146
molecular cloud and present a preliminary analysis of the filamentary structure in this region …

We address the problem of the origin of massive stars, namely the origin, path, and
timescale of the mass flows that create them. Based on extensive numerical simulations, we …
