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…
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…
Herschel survey of brown dwarf disks in Rho Ophiuchi
C. Alves de Oliveira, P. Ábrahám, G. Marton +6
Recent observations of the Rho Ophiuchi cluster with the Herschel Space Observatory allow us to probe the spectral energy distribution (SED) of the brown dwarf population in the fa…
Variation in dust properties in a dense filament of the Taurus molecular complex (L1506)
Nathalie Ysard, Alain Abergel, Isabelle Ristorcelli +6
We observed the L1506 filament, which is located in the Taurus molecular complex, with the Herschel PACS and SPIRE instruments. Our aim is to prove the variation in grain propertie…
Dense cores in the dark cloud complex LDN1188
E. Verebélyi, V. Könyves, S. Nikolić +4
We present a molecular line emission study of the LDN1188 dark cloud complex located in Cepheus. In this work we focused on the densest parts of the cloud and on the close neighbou…
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…
Determination of the far-infrared dust opacity in a prestellar core
Aleksi Suutarinen, Lauri K. Haikala, Jorma Harju +5
(abridged) We correlated near-infrared stellar H-Ks colour excesses of background stars from NTT/SOFI with the far-IR optical depth map, tauFIR, derived from Herschel 160, 250, 350…
The Herschel Gould Belt Survey in Chamaeleon II - Properties of cold dust in disks around young stellar objects
L. Spezzi, N. L. J. Cox, T. Prusti +14
We report on the Herschel Gould Belt survey (HGBS) of ChaII, focusing on the detection of Class I to III young stellar objects (YSOs). We aim at characterizing the circumstellar ma…
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…
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…
