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 …

Star-forming gas clouds are strongly magnetized, and their ionization fractions are high
enough to place them close to the regime of ideal magnetohydrodyamics on all but 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 …

The enormous radiative and mechanical luminosities of massive stars impact a vast range of
scales and processes, from the reionization of the universe, to the evolution of galaxies, to …

Whether or not molecular clouds and embedded cloud fragments are stable against
collapse is of utmost importance for the study of the star formation process. Only" …

Chemistry plays a key role in many astrophysical situations regulating the cooling and the
thermal properties of the gas, which are relevant during gravitational collapse, the evolution …

Recent observations suggest an that intensive molecular cloud collision can trigger massive
star/cluster formation. The most important physical process caused by the collision is a …

Context. Theoretical studies of collapsing clouds have found that even a relatively weak
magnetic field may prevent the formation of disks and their fragmentation. However, most …

Context. Massive stars form in magnetized and turbulent environments and are often located
in stellar clusters. The accretion and outflows mechanisms associated with forming massive …

Context. There is growing evidence that massive stars grow by disk accretion in a similar
way to their low-mass counterparts. Early in evolution, these disks can achieve masses that …
