From Filamentary Networks to Dense Cores in Molecular Clouds: Toward a New Paradigm for Star Formation
Philippe André, James Di Francesco, Derek Ward-Thompson +3
Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths with the Herschel Space Observatory have provided us with unprecedented images of the i…
A Roadmap for Canadian Submillimetre Astronomy
Tracy Webb, Scott Chapman, James Di Francesco +4
We survey the present landscape in submillimetre astronomy for Canada and describe a plan for continued engagement in observational facilities to ~2020. Building on Canada's decada…
Pillars and globules at the edges of H ii regions, Confronting Herschel observations and numerical simulations
P. Tremblin, V. Minier, N. Schneider +24
Pillars and globules are present in many high-mass star-forming regions, such as the Eagle nebula (M16) and the Rosette molecular cloud, and understanding their origin will help ch…
Water and Methanol Maser Survey of Protostars in the Orion Molecular Cloud Complex
Miju Kang, Jeong-Eun Lee, Minho Choi +4
The results of a maser survey toward ninety-nine protostars in the Orion molecular cloud complex are presented. The target sources are low-mass protostars identified from infrared…
Alignment in star-debris disc systems seen by Herschel
J. S. Greaves, G. M. Kennedy, N. Thureau +28
Many nearby main-sequence stars have been searched for debris using the far-infrared Herschel satellite, within the DEBRIS, DUNES and Guaranteed-Time Key Projects. We discuss here…
Two Mass Distributions in the L 1641 Molecular Clouds: The Herschel connection of Dense Cores and Filaments in Orion A
D. Polychroni, E. Schisano, D. Elia +23
We present the Herschel Gould Belt survey maps of the L1641 molecular clouds in Orion A. We extracted both the filaments and dense cores in the region. We identified which of dense…
Correlating Infall with Deuterium Fractionation in Dense Cores
Scott Schnee, Nathan Brunetti, James Di Francesco +4
We present a survey of HCO+ (3-2) observations pointed towards dense cores with previous measurements of N(N2D+)/N(N2H+). Of the 26 cores in this survey, five show the spectroscopi…
Abundant cyanopolyynes as a probe of infall in the Serpens South cluster-forming region
R. K. Friesen, L. Medeiros, S. Schnee +4
We have detected bright HC7N J = 21-20 emission toward multiple locations in the Serpens South cluster-forming region using the K-Band Focal Plane Array at the Robert C. Byrd Green…
Herschel Reveals Massive Cold Clumps in NGC 7538
C. Fallscheer, M. A. Reid, J. Di Francesco +29
We present the first overview of the Herschel observations of the nearby high-mass star-forming region NGC 7538, taken as part of the Herschel imaging study of OB Young Stellar obj…
First results from the Herschel Gould Belt Survey in Taurus
J. M. Kirk, D. Ward-Thompson, P. Palmeirim +26
The whole of the Taurus region (a total area of 52 sq. deg.) has been observed by the Herschel SPIRE and PACS instruments at wavelengths of 70, 160, 250, 350 and 500 μm as part of…
The Herschel and JCMT Gould Belt Surveys: Constraining Dust Properties in the Perseus B1 Clump with PACS, SPIRE, and SCUBA-2
S. I. Sadavoy, J. Di Francesco, D. Johnstone +27
We present Herschel observations from the Herschel Gould Belt Survey and SCUBA-2 science verification observations from the JCMT Gould Belt Survey of the B1 clump in the Perseus mo…
A Herschel and APEX Census of the Reddest Sources in Orion: Searching for the Youngest Protostars
Amelia M. Stutz, John J. Tobin, Thomas Stanke +13
We perform a census of the reddest, and potentially youngest, protostars in the Orion molecular clouds using data obtained with the PACS instrument onboard the Herschel Space Obser…
