Recent observations have suggested that circumstellar disks may commonly form around
young stellar objects. Although the formation of circumstellar disks can be a natural result of …

Binary formation is an important aspect of star formation. One possible route for close-in
binary formation is disk fragmentation,–. Recent observations show that small-scale …

The envelopes and disks that surround protostars reflect the initial conditions of star and
planet formation and govern the assembly of stellar masses. Characterizing these structures …

Planet formation in protoplanetary discs requires dust grains to coagulate from the sub-
micron sizes that are found in the interstellar medium into much larger objects. For the first …

Abstract We present Markov Chain Monte Carlo radiative transfer modeling of a joint ALMA
345 GHz and spectral energy distribution data set for a sample of 97 protostellar disks from …

Context. Planets form in protoplanetary discs. Their masses, distribution, and orbits
sensitively depend on the structure of the protoplanetary discs. However, what sets the initial …

We present results from the first radiation non-ideal magnetohydrodynamics (MHD)
simulations of low-mass star cluster formation that resolve the fragmentation process down …

We use a 3D radiative non-ideal magnetohydrodynamic simulation to investigate the
formation and evolution of a young protostellar disc from a magnetized pre-stellar core. The …

Magnetic fields play an important role in the dynamics of present-day molecular clouds.
Recent work has shown that magnetic fields are equally important for primordial clouds …

Non-ideal magnetohydrodynamic (MHD) processes–namely Ohmic resistivity, ambipolar
diffusion, and the Hall effect–modify the early stages of the star formation process and the …
