Stars are among the most fundamental structures of our Universe. They comprise most of the
baryonic and luminous mass of galaxies; synthesize heavy elements; and inject mass …

Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths
with the Herschel Space Observatory have provided us with unprecedented images of the …

We review the role that magnetic field may have on the formation and evolution of molecular
clouds. After a brief presentation and main assumptions leading to ideal MHD equations …

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 …

Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

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 …

The stellar initial mass function (IMF) in the early universe is essential to understand the
formation of ancient galaxies. To this end, we conduct a series of long-term radiation …

We study star cluster formation in a low-metallicity environment using three-dimensional
hydrodynamic simulations. Starting from a turbulent cloud core, we follow the formation and …

Stars form within molecular clouds but our understanding of this fundamental process
remains hampered by the complexity of the physics that drives their evolution. We review our …

We demonstrate with a new three-dimensional adaptive mesh refinement code that
perturbations arising from discretization of the equations of self-gravitational hydrodynamics …
