This review examines observations of magnetic fields in molecular clouds and what those
observations tell us about the theory of molecular cloud evolution and star formation. First …

▪ Abstract This review surveys the observed properties of interstellar dust grains: the
wavelength-dependent extinction of starlight, including absorption features, from UV to …

In this chapter we review recent advances in understanding the roles that magnetic fields
play throughout the star formation process, gained through observations and simulations of …

We report high-angular-resolution measurements of polarized dust emission toward the low-
mass protostellar system NGC 1333 IRAS 4A. We show that in this system the observed …

The mechanisms causing millimeter-wave polarization in protoplanetary disks are under
debate. To disentangle the polarization mechanisms, we observe the protoplanetary disk …

ABSTRACT Massive stars (M> 8 M☉) typically form in parsec-scale molecular clumps that
collapse and fragment, leading to the birth of a cluster of stellar objects. We investigate the …

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 …

We describe a method for determining the dispersion of magnetic field vectors about large-
scale fields in turbulent molecular clouds. The method is designed to avoid inaccurate …

Massive stars play a crucial role in the production of heavy elements and in the evolution of
the interstellar medium, yet how they form is still a matter of debate. We report high-angular …

Abstract The Davis–Chandrasekhar–Fermi (DCF) method provides an indirect way to
estimate the magnetic field strength from statistics of magnetic field orientations. We compile …
