Laboratory facilities employing high pulsed currents and voltages, and called generally
“pulsed-power facilities,” allow experimenters to produce a variety of hydrodynamical …

Over the past three decades, we have witnessed one of the great revolutions in our
understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just …

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 …

In many ways the discovery that star formation involves outflow as well as inflow from
gravitational collapse marked the beginning of modern studies of the assembly of stars. Jets …

The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of
Seyfert galaxies is a well established observational fact. This material is systematically …

Powerful jets and outflows are launched from the protostellar disks around newborn stars.
These outflows carry enough mass and momentum to transform the structure of their parent …

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 …

Magnetohydrodynamic (MHD) and photoevaporative winds are thought to play an important
role in the evolution and dispersal of planet-forming disks. We report the first high-resolution …

We study the evolution and final dispersal of protoplanetary discs that evolve under the
action of internal and external photoevaporation, and different degrees of viscous transport …

The surroundings of massive protostars constitute an accretion disc which has numerically
been shown to be subject to fragmentation and responsible for luminous accretion-driven …
