Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

We present results from the first population synthesis study of protostellar discs. We analyse
the evolution and properties of a large sample of protostellar discs formed in a radiation …

Context. Understanding the formation mechanisms of protoplanetary disks and multiple
systems and also their pristine properties are key questions for modern astrophysics. The …

Emission from protostars at centimeter radio wavelengths has been shown to trace the free–
free emission arising from ionizing shocks as a result of jets and outflows driven by …

Context. Theoretical studies of collapsing clouds have found that even a relatively weak
magnetic field may prevent the formation of disks and their fragmentation. However, most …

Context. Complex organic molecules (COMs) have been detected in a few Class 0
protostars but their origin is not well understood. While the usual picture of a hot corino …

We present λ 1.3 mm Combined Array for Research in Millimeter-wave Astronomy
observations of dust polarization toward 30 star-forming cores and eight star-forming regions …

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 have conducted a survey of 328 protostars in the Orion molecular clouds with the
Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of∼ 0 farcs 1 (40 …
