Reconstructing the density and temperature structure of prestellar cores from data: A case study for B68 and L1689B
A. Roy, Ph. Andre', P. Palmeirim +22
Utilizing multi-wavelength dust emission maps acquired with , we reconstruct local volume density and dust temperature profiles for the prestellar cores B68 and L1689B us…
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…
SDC13 infrared dark clouds: Longitudinally collapsing filaments?
N. Peretto, G. A. Fuller, Ph. André +11
Formation of stars is now believed to be tightly linked to the dynamical evolution of interstellar filaments in which they form. In this paper we analyze the density structure and…
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…
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…
What determines the density structure of molecular clouds ? A case study of Orion B with Herschel
N. Schneider, Ph. Andre, V. Konyves +19
A key parameter to the description of all star formation processes is the density structure of the gas. In this letter, we make use of probability distribution functions (PDFs) of…
Formation and evolution of interstellar filaments; Hints from velocity dispersion measurements
Doris Arzoumanian, Philippe André, Nicolas Peretto +1
We investigate the gas velocity dispersions of a sample of filaments recently detected as part of the Herschel Gould Belt Survey in the IC5146, Aquila, and Polaris interstellar clo…
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…
Herschel Observations of the W3 GMC: Clues to the Formation of Clusters of High-Mass Stars
A. Rivera-Ingraham, P. G. Martin, D. Polychroni +22
The W3 GMC is a prime target for the study of the early stages of high-mass star formation. We have used Herschel data from the HOBYS key program to produce and analyze column dens…
