Observational advances over the last decade have enabled high-resolution, interferometric
studies of forming multiple systems, statistical surveys of multiplicity in star-forming regions …

We review the role of stellar flybys and encounters in shaping planet-forming discs around
young stars, based on the published literature on this topic in the last 30 years. Since most …

We report spectro-polarimetric results of an observational campaign of the bright neutron
star low-mass X-ray binary Cyg X-2 simultaneously observed by IXPE, NICER, and …

Context. Rotationally supported disks are critical in the star formation process. The questions
of when they form and what factors influence or hinder their formation have been studied but …

We present a multiplicity study of all known protostars (94) in the Perseus molecular cloud
from a Karl G. Jansky Very Large Array survey at Ka-band (8 mm and 1 cm) and C-band (4 …

We characterize protostellar multiplicity in the Orion molecular clouds using Atacama Large
Millimeter/submillimeter Array 0.87 mm and Very Large Array 9 mm continuum surveys …

Abstract We present 0 farcs 25 resolution (35 au) ALMA 1.3 mm dust polarization
observations for 37 young stellar objects (YSOs) in the Ophiuchus molecular cloud. These …

We present the full disk-fit results VANDAM survey of all Class 0 and I protostars in the
Perseus molecular cloud. We have 18 new protostellar disk candidates around Class 0 and I …

The protostellar outflows of wide-separation forming binaries frequently appear misaligned.
We use magneto-hydrodynamic simulations to investigate the alignment of protostellar spin …

The initial multiplicity of stellar systems is highly uncertain. A number of mechanisms have
been proposed to explain the origin of binary and multiple star systems, including core …
