Of the over 150 different molecular species detected in the interstellar and circumstellar
media, approximately 50 contain 6 or more atoms. These molecules, labeled complex by …

▪ 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 …

We present a census of molecular outflows across four active regions of star formation in the
Perseus molecular cloud (NGC 1333, IC348/HH211, L1448 and L1455), totalling an area of …

▪ Abstract Outflow activity is associated with all stages of early stellar evolution, from deeply
embedded protostellar objects to visible young stars. Herbig-Haro (HH) objects are 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 …

▪ 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 …

Millimeter and submillimeter line surveys of the protobinary source IRAS 16293-2422 are
presented in the 230 and 345 GHz windows. In total, 265 lines belonging to 44 molecules …

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 …

We present the first results from a recent survey of molecular lines in L1157, a highly
collimated bipolar molecular outflow driven by a class 0 protostar. These observations are …

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 …
