Feedback of molecular outflows from protostars in NGC 1333, revealed by Herschel and Spitzer spectro-imaging observations

Odysseas Dionatos, Lars. E. Kristensen, Mario Tafalla +2

Large scale spectral maps of star forming regions enable the comparative study of the gas excitation around an ensemble of sources at a common frame of reference, providing direct…

The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars I. Identifying and Characterizing the Protostellar Content of the OMC2-FIR4 and OMC2-FIR3 Regions

John J. Tobin, S. Thomas Megeath, Merel van 't Hoff +31

We present ALMA (0.87~mm) and VLA (9~mm) observations toward OMC2-FIR4 and OMC2-FIR3 within the Orion integral-shaped filament that are thought to be the nearest regions of interme…

A Triple Protostar System Formed via Fragmentation of a Gravitationally Unstable Disk

John Tobin, Kaitlin Kratter, Magnus Persson +9

Binary and multiple star systems are a frequent outcome of the star formation process, and as a result, almost half of all sun-like stars have at least one companion star. Theoreti…

High DO/HDO ratio in the inner regions of the low-mass protostar NGC1333 IRAS2A

Audrey Coutens, Jes Jørgensen, Magnus Persson +3

Water plays a crucial role both in the interstellar medium and on Earth. To constrain its formation mechanisms and its evolution through the star formation process, the determinati…

Missing water in Class I protostellar disks

Daniel Harsono, Magnus Persson, Alyssa Ramos +10

Water is a key volatile that provides insights into the initial stages of planet formation. The low water abundances inferred from water observations toward low-mass protostellar o…

The VLA/ALMA Nascent Disk and Multiplicity (VANDAM) Survey of Orion Protostars. A Statistical Characterization of Class 0 and I Protostellar Disks

John J. Tobin, Patrick Sheehan, S. Thomas Megeath +33

We have conducted a survey of 328 protostars in the Orion molecular clouds with ALMA at 0.87 mm at a resolution of 0.1" (40 au), including observations with the VLA at 9 mm t…
