▪ Abstract Recent advances in the understanding of the chemical processes that occur
during all stages of the formation of stars, from the collapse of molecular clouds to the …

▪ Abstract A violent outflow of high-velocity gas is one of the first manifestations of the
formation of a new star. Such outflows emerge bipolarly from the young object and involve …

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

The last decade has witnessed significant advances in our observational understanding of
the earliest stages of low-mass star formation. The advent of sensitive receivers on large …

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 …

The chemistry of developing and collapsing low-mass protostellar cores is followed using a
chemical code with a time-varying density. Two evolutionary scenarios are represented …

We report the results of a millimeter interferometric survey of compact 3 mm continuum
sources in the inner 5 &farcm; 5× 5 &farcm; 5 region of the Serpens core. We detect 32 …

Aims. As a part of the CALYPSO Large Program, we aim to constrain the properties of
protostellar jets and outflows by searching for corresponding emission in a sample of 21 …

Context. Analyzing the properties of dust and its evolution in the early phases of star
formation is crucial to put constraints on the collapse and accretion processes as well as on …

Molecular line surveys and fully sampled spectral line maps at 1.3 and 0.87 mm are used to
examine the physical and chemical characteristics of the extreme Class I sources IRAS 4A …
