Gas dynamics in Massive Dense Cores in Cygnus-X
T. Csengeri, S. Bontemps, N. Schneider +2
We study the kinematic properties of dense gas surrounding massive protostars recognized by Bontemps et a. (2010) in a sample of five Massive Dense Cores in Cygnus-X. We investigat…
A Spitzer View of Star Formation in the Cygnus X North Complex
I. M. Beerer, X. P. Koenig, J. L. Hora +17
We present new images and photometry of the massive star forming complex Cygnus X obtained with IRAC and MIPS on the Spitzer Space Telescope. A combination of IRAC, MIPS, UKIDSS, a…
From filamentary clouds to prestellar cores to the stellar IMF: Initial highlights from the Herschel Gould Belt survey
Ph. André, A. Men'shchikov, S. Bontemps +54
We summarize the first results from the Gould Belt survey, obtained toward the Aquila Rift and Polaris Flare regions during the 'science demonstration phase' of Herschel. Our 70-50…
Herschel Observations of the W43 "mini-starburst"
J. Bally, L. D. Anderson, C. Battersby +20
Aims: To explore the infrared and radio properties of one of the closest Galactic starburst regions. Methods: Images obtained with the Herschel Space Observatory at wavelengths of…
Clouds, filaments and protostars: the Herschel Hi-GAL Milky Way
S. Molinari, B. Swinyard, J. Bally +121
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key-project that will map the inner Galactic Plane of the Milky Way in 5 bands…
Filamentary structures and compact objects in the Aquila and Polaris clouds observed by Herschel
A. Men'shchikov, Ph. André, P. Didelon +36
Our PACS and SPIRE images of the Aquila Rift and part of the Polaris Flare regions, taken during the science demonstration phase of Herschel discovered fascinating, omnipresent fil…
Physical properties of the Sh2-104 HII region as seen by Herschel
J. A. Rodón, A. Zavagno, J. -P. Baluteau +46
Context: Sh2-104 is a Galactic H ii region with a bubble morphology, detected at optical and radio wavelengths. It is considered the first observational confirmation of the collect…
The Aquila prestellar core population revealed by Herschel
V. Könyves, Ph. André, A. Men'shchikov +37
The origin and possible universality of the stellar initial mass function (IMF) is a major issue in astrophysics. One of the main objectives of the Herschel Gould Belt Survey is to…
Herschel-SPIRE spectroscopy of the DR21 molecular cloud core
Glenn J. White, A. Abergel, L. Spencer +47
We present far-infrared spectra and maps of the DR21 molecular cloud core between 196 and 671 microns, using the Herschel-SPIRE spectrometer. Nineteen molecular lines originating f…
The Herschel first look at protostars in the Aquila Rift
S. Bontemps, Ph. Andre, V. Konyves +40
As part of the science demonstration phase of the Herschel mission of the Gould Belt Key Program, the Aquila Rift molecular complex has been observed. The complete ~ 3.3deg x 3.3de…
First detection of the Methylidyne cation (CH+) fundamental rotational line with the Herschel/SPIRE FTS
D. A. Naylor, E. Dartois, E. Habart +41
Aims. To follow the species chemistry arising in diverse sources of the Galaxy with Herschel. Methods. SPIRE FTS sparse sampled maps of the Orion bar & compact HII regions G29.96-0…
The physical properties of the dust in the RCW 120 HII region as seen by Herschel
L. D. Anderson, A. Zavagno, J. A. Rodon +41
Context. RCW 120 is a well-studied, nearby Galactic HII region with ongoing star formation in its surroundings. Previous work has shown that it displays a bubble morphology at mid-…
Circumstellar Structure around Evolved Stars in the Cygnus-X Star Formation Region
Kathleen E. Kraemer, Joseph L. Hora, Michael P. Egan +15
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the C…
Dynamic star formation in the massive DR21 filament
N. Schneider, T. Csengeri, S. Bontemps +5
The formation of massive stars is a highly complex process in which it is not clear whether the star-forming gas is in global gravitational collapse or in an equilibrium state, sup…
Toward understanding the formation of multiple systems - A pilot IRAM-PdBI survey of Class 0 objects
A. J. Maury, Ph. Andre, P. Hennebelle +6
The formation process of binary stars and multiple systems is poorly understood. Here, we seek to determine the typical outcome of protostellar collapse and to constrain models of…
The link between molecular cloud structure and turbulence
N. Schneider, S. Bontemps, R. Simon +7
We aim to better understand how the spatial structure of molecular clouds is governed by turbulence. For that, we study the large-scale spatial distribution of low density molecula…
