Detection of HF emission from the Orion Bar
F. F. S. van der Tak, V. Ossenkopf, Z. Nagy +3
The clumpy density structure of photon-dominated regions is well established, but the physical properties of the clumps and of the surrounding interclump medium are only approximat…
Multilayer modeling of porous grain surface chemistry I. The GRAINOBLE model
Vianney Taquet, Cecilia Ceccarelli, Claudine Kahane
Mantles of iced water, mixed with CO, H2CO, and CH3OH are formed during the so called prestellar core phase. In addition, radicals are also thought to be formed on the grain surfac…
Nitrogen hydrides and the H2 ortho-to-para ratio in dark clouds
Vincent Dislaire, Pierre Hily-Blant, Alexandre Faure +3
Nitrogen bearing species are common tracers of the physical conditions in a wide variety of objects, and most remarkably in dark clouds. The reservoir of gaseous nitrogen is expect…
A Herschel Search For Cold Dust in Brown Dwarf Disks: First Results
Paul M. Harvey, Thomas Henning, Francois Menard +7
We report initial results from a {\it Herschel} program to search for far-infrared emission from cold dust around a statistically significant sample of young brown dwarfs. The firs…
The Ubiquity of Micrometer-Sized Dust Grains in the Dense Interstellar Medium
Laurent Pagani, Jürgen Steinacker, Aurore Bacmann +2
Cold molecular clouds are the birthplaces of stars and planets, where dense cores of gas collapse to form protostars. The dust mixed in these clouds is thought to be made of grains…
Spitzer IRS Detection of Molecular Hydrogen Rotational Emission Towards Translucent Clouds
James G. Ingalls, T. M. Bania, F. Boulanger +3
Using the Infrared Spectrograph on board the Spitzer Space Telescope, we have detected emission in the S(0), S(1), and S(2) pure-rotational (v=0-0) transitions of molecular hydroge…
First detection of Hydrogen Chloride towards protostellar shocks
C. Codella, C. Ceccarelli, S. Bottinelli +8
We present the first detection of hydrogen chlorine in a protostellar shock, by observing the fundamental transition at 626 GHz with the Herschel HIFI spectrometer. We detected two…
Herschel Observations of the T Cha Transition Disk: Constraining the Outer Disk Properties
Lucas A. Cieza, Johan Olofsson, Paul M. Harvey +7
T Cha is a nearby (d = 100 pc) transition disk known to have an optically thin gap separating optically thick inner and outer disk components. Huelamo et al. (2011) recently report…
L1157-B1: Water and ammonia as diagnostics of shock temperature
S. Viti, I. Jimenez-Serra, J. A. Yates +5
We investigate the origin and nature of the profiles of water and ammonia observ ed toward the L1157-B1 clump as part of the HIFI CHESS survey (Ceccarelli et al. 2010) using a new…
The dynamical state of stellar structure in star-forming regions
J. M. Diederik Kruijssen, Thomas Maschberger, Nickolas Moeckel +3
The fraction of star formation that results in bound star clusters is influenced by the density spectrum in which stars are formed and by the response of the stellar structure to g…
Hydrogen cyanide and isocyanide in prestellar cores
M. Padovani, C. M. Walmsley, M. Tafalla +2
We studied the abundance of HCN, H13CN, and HN13C in a sample of prestellar cores, in order to search for species associated with high density gas. We used the IRAM 30m radiotelesc…
Supernova enhanced cosmic ray ionization and induced chemistry in a molecular cloud of W51C
C. Ceccarelli, P. Hily-Blant, T. Montmerle +3
Cosmic rays pervade the Galaxy and are thought to be accelerated in supernova shocks. The interaction of cosmic rays with dense interstellar matter has two important effects: 1) hi…
Disk and Envelope Structure in Class 0 Protostars: II. High Resolution Millimeter Mapping of the Serpens Sample
M. L. Enoch, S. Corder, G. Duchene +13
We present high-resolution CARMA 230 GHz continuum imaging of nine deeply embedded protostars in the Serpens Molecular Cloud, including six of the nine known Class 0 protostars in…
Global mass segregation in hydrodynamical simulations of star formation
Th. Maschberger, C. J. Clarke
Recent analyses of mass segregation diagnostics in star forming regions invite a comparison with the output of hydrodynamic simulations of star formation. In this work we investiga…
Detection of CH+ emission from the disc around HD100546
W. -F. Thi, F. Ménard, G. Meeus +13
Despite its importance in the thermal-balance of the gas and in the determination of primeval planetary atmospheres, the chemistry in protoplanetary discs remains poorly constraine…
TIMASSS: The IRAS16293-2422 Millimeter And Submillimeter Spectral Survey. I. Observations, calibration and analysis of the line kinematics
E. Caux, C. Kahane, A. Castets +15
While unbiased surveys observable from ground-based telescopes have previously been obtained towards several high mass protostars, very little exists on low mass protostars. To fil…
Tracing the Energetics and Evolution of Dust with Spitzer: a Chapter in the History of the Eagle Nebula
N. Flagey, F. Boulanger, A. Noriega-Crespo +5
The Spitzer GLIMPSE and MIPSGAL surveys have revealed a wealth of details of the Galactic plane. We use them to study the energetics and dust properties of M16, one of the best kno…
A dual-frequency sub-arcsecond study of proto-planetary disks at mm wavelengths: First evidence for radial variations of the dust properties
S. Guilloteau, A. Dutrey, V. Piétu +1
(Abridged) We attempt to characterize the radial distribution of dust in disks around a sample of young stars from an observational point of view, and, when possible, in a model-in…

B. Lefloch, J. Cernicharo, S. Pacheco +1
Previous far-infrared observations at low-angular resolution have reported the presence of water associated with low-velocity outflow shocks and protostellar envelopes. The outflow…
