Multi-scale analysis of the Monoceros OB 1 star-forming region: II. Colliding filaments in the Monoceros OB1 molecular cloud
Julien Montillaud, Mika Juvela, Charlotte Vastel +24
We started a multi-scale analysis of G202.3+2.5, an intertwined filamentary region of Monoceros OB1. In Paper I, we examined the distributions of dense cores and protostars and fou…
Multi-scale analysis of the Monoceros OB 1 star-forming region: I. The dense core population
Julien Montillaud, Mika Juvela, Charlotte Vastel +24
Current theories and models attempt to explain star formation globally, from core scales to giant molecular cloud scales. A multi-scale observational characterisation of an entire…
Sulfur-Bearing Species Tracing the Disk/Envelope System in the Class I Protostellar Source Elias 29
Yoko Oya, Ana López-Sepulcre, Nami Sakai +11
We have observed the Class I protostellar source Elias 29 with Atacama Large Millimeter/submillimeter Array (ALMA). We have detected CS, SO, SO, SO, and SiO line emissio…
Isocyanogen formation in the cold interstellar medium
Charlotte Vastel, Jean-Christophe Loison, Valentine Wakelam +1
Cyanogen (NCCN) is the simplest member of the dicyanopolyynes group, and has been proposed as a major source of the CN radical observed in cometary atmospheres. Although not detect…
Efficient methanol production on the dark side of a prestellar core
Jorma Harju, Jaime E. Pineda, Anton I. Vasyunin +23
We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense co…
SCOPE: SCUBA-2 Continuum Observations of Pre-protostellar Evolution - Survey Description and Compact Source Catalogue
D. J. Eden, Tie Liu, Kee-Tae Kim +157
We present the first release of the data and compact-source catalogue for the JCMT Large Program SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE). SCOPE consist…
