The role of magnetic fields in setting the star formation rate and the initial mass function

MR Krumholz, C Federrath - Frontiers in Astronomy and Space …, 2019 - frontiersin.org
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 …

Interferometric observations of magnetic fields in forming stars

CLH Hull, Q Zhang - Frontiers in Astronomy and Space Sciences, 2019 - frontiersin.org
The magnetic field is a key ingredient in the recipe of star formation. However, the
importance of the magnetic field in the early stages of the formation of low-and high-mass …

Gravity-driven magnetic field at∼ 1000 au scales in high-mass star formation

P Sanhueza, JM Girart, M Padovani… - The Astrophysical …, 2021 - iopscience.iop.org
A full understanding of high-mass star formation requires the study of one of the most elusive
components of the energy balance in the interstellar medium: magnetic fields. We report …

Using Herschel and Planck observations to delineate the role of magnetic fields in molecular cloud structure

JD Soler - Astronomy & Astrophysics, 2019 - aanda.org
We present a study of the relative orientation between the magnetic field projected onto the
plane of sky (B⊥) on scales down to 0.4 pc, inferred from the polarized thermal emission of …

Impact of protostellar outflows on turbulence and star formation efficiency in magnetized dense cores

SSR Offner, J Chaban - The Astrophysical Journal, 2017 - iopscience.iop.org
The star-forming efficiency of dense gas is thought to be set within cores by outflow and
radiative feedback. We use magnetohydrodynamic simulations to investigate the relation …

Zooming in on individual star formation: low-and high-mass stars

AL Rosen, SSR Offner, SI Sadavoy, A Bhandare… - Space Science …, 2020 - Springer
Star formation is a multi-scale, multi-physics problem ranging from the size scale of
molecular clouds (∼ 10 ∼10 s pc) down to the size scales of dense prestellar cores (∼ 0.1 …

ALMA observations of polarization from dust scattering in the IM Lup protoplanetary disk

CLH Hull, H Yang, ZY Li, A Kataoka… - The Astrophysical …, 2018 - iopscience.iop.org
We present 870 μm ALMA observations of polarized dust emission toward the Class II
protoplanetary disk IM Lup. We find that the orientation of the polarized emission is along the …

Protostellar birth with ambipolar and ohmic diffusion

N Vaytet, B Commerçon, J Masson, M González… - Astronomy & …, 2018 - aanda.org
Context. The transport of angular momentum is fundamental during the formation of low-
mass stars; too little removal and rotation ensures stellar densities are never reached, too …

Modeling accretion shocks at the disk–envelope interface-Sulfur chemistry

ML van Gelder, B Tabone, EF van Dishoeck… - Astronomy & …, 2021 - aanda.org
Context. As material from an infalling protostellar envelope hits the forming disk, an
accretion shock may develop which could (partially) alter the envelope material entering the …

Distribution of velocity gradient orientations: Mapping magnetization with the velocity gradient technique

A Lazarian, KH Yuen, KW Ho, J Chen… - The Astrophysical …, 2018 - iopscience.iop.org
Recent developments of the velocity gradient technique (VGT) show that the velocity
gradients provide a reliable tracing of the magnetic field direction in turbulent plasmas. In …
