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 …

We analyse the first giant molecular cloud (GMC) simulation to follow the formation of
individual stars and their feedback from jets, radiation, winds, and supernovae, using the …

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 …

ABSTRACT We present STARFORGE (STAR FORmation in Gaseous Environments): a new
numerical framework for 3D radiation magnetohydrodynamic (MHD) simulations of star …

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 …

One of the key mysteries of star formation is the origin of the stellar initial mass function
(IMF). The IMF is observed to be nearly universal in the Milky Way and its satellites, and …

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 …

The characteristic mass that sets the peak of the stellar initial mass function (IMF) is closely
linked to the thermodynamic behaviour of interstellar gas, which controls how gas fragments …

We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using
observations from Spitzer (143), the US Naval Observatory (18), the New Technology …

The initial mass function (IMF) of stars is a key quantity affecting almost every field of
astrophysics, yet it remains unclear what physical mechanisms determine it. We present the …
