The relation between accretion rates and the initial mass function in hydrodynamical simulations of star formation
Th. Maschberger, I. A. Bonnell, C. J. Clarke +1
We analyse a hydrodynamical simulation of star formation. Sink particles in the simulations which represent stars show episodic growth, which is presumably accretion from a core th…
On the mass function of stars growing in a flocculent medium
Thomas Maschberger
Stars form in regions of very inhomogeneous densities and may have chaotic orbital motions. This leads to a time variation of the accretion rate, which will spread the masses over…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Planck Collaboration, A. Abergel, P. A. R. Ade +196
The dust-HI correlation is used to characterize the emission properties of dust in the diffuse interstellar medium. We cross-correlate sky maps from Planck, WMAP, and DIRBE, at 17…
Planck 2013 results. XI. All-sky model of thermal dust emission
Planck Collaboration, A. Abergel, P. A. R. Ade +244
This paper presents an all-sky model of dust emission from the Planck 857, 545 and 353 GHz, and IRAS 100 micron data. Using a modified black-body fit to the data we present all-sky…
CII in the Interstellar Medium: Excitation by H2 Revisited
Laurent Wiesenfeld, Paul F. Goldsmith
C is a critical constituent of many regions of the interstellar medium, as it can be a major reservoir of carbon and, under a wide range of conditions, the dominant gas coolant…
CO ro-vibrational lines in HD100546: A search for disc asymmetries and the role of fluorescence
R. P. Hein Bertelsen, I. Kamp, M. Goto +5
We have studied the emission of CO ro-vibrational lines in the disc around the Herbig Be star HD100546 with the final goal of using these lines as a diagnostic to understand inner…
The CHESS survey of the L1157-B1 bow-shock: high and low excitation water vapor
G. Busquet, B. Lefloch, M. Benedettini +9
Molecular outflows powered by young protostars strongly affect the kinematics and chemistry of the natal molecular cloud through strong shocks resulting in substantial modification…
Spatially extended OH+ emission from the Orion Bar and Ridge
Floris van der Tak, Zsofia Nagy, Volker Ossenkopf +5
We report the first detection of a Galactic source of OH+ line emission: the Orion Bar, a bright nearby photon-dominated region. Line emission is detected over ~1' (0.12 pc), traci…
Scattering from dust in molecular clouds: Constraining the dust grain size distribution through near-infrared cloudshine and infrared coreshine
M. Andersen, J. Steinacker, W-F. Thi +3
Context. The largest grains (0.5-1 micron) in the interstellar size distribution are efficient in scattering near- and mid-infrared radiation. These wavelengths are therefore parti…
The IRAM-30m line survey of the Horsehead PDR: IV. Comparative chemistry of H2CO and CH3OH
V. V. Guzman, J. R. Goicoechea, J. Pety +6
Aims. We investigate the dominant formation mechanism of H2CO and CH3OH in the Horsehead PDR and its associated dense core. Methods. We performed deep integrations of several H2CO…
Deuterated water in the solar-type protostars NGC 1333 IRAS 4A and IRAS 4B
A. Coutens, C. Vastel, S. Cabrit +19
Aims. The aim of this paper is to study deuterated water in the solar-type protostars NGC1333 IRAS4A and IRAS4B, to compare their HDO abundance distribution with other star-forming…
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…
The diagnostic potential of Fe lines applied to protostellar jets
T. Giannini, B. Nisini, S. Antoniucci +6
We investigate the diagnostic capabilities of the iron lines for tracing the physical conditions of the shock-excited gas in jets driven by pre-main sequence stars. We have analyze…
Gas lines from the 5-Myr old optically thin disk around HD141569A. Herschel observations and modeling
Wing-Fai Thi, Christophe Pinte, Eric Pantin +20
At the distance of 99-116 pc, HD141569A is one of the nearest HerbigAe stars that is surrounded by a tenuous disk, probably in transition between a massive primordial disk and a de…
Chemical modeling of the L1498 and L1517B prestellar cores: CO and HCO+ depletion
S. Maret, E. A Bergin, M. Tafalla
Prestellar cores exhibit a strong chemical differentiation, which is mainly caused by the freeze-out of molecules onto the grain surfaces. Understanding this chemical structure is…
The B1 shock in the L1157 outflow as seen at high spatial resolution
M. Benedettini, S. Viti, C. Codella +7
We present high spatial resolution (750 AU at 250 pc) maps of the B1 shock in the blue lobe of the L1157 outflow in four lines: CS (3-2), CH3OH (3_K-2_K), HC3N (16-15) and p-H2CO (…
Planck intermediate results. XV. A study of anomalous microwave emission in Galactic clouds
Planck Collaboration, P. A. R. Ade, N. Aghanim +180
Anomalous microwave emission (AME) is believed to be due to electric dipole radiation from small spinning dust grains. The aim of this paper is a statistical study of the basic pro…
Broad N2H+ emission towards the protostellar shock L1157-B1
C. Codella, S. Viti, C. Ceccarelli +8
We present the first detection of N2H+ towards a low-mass protostellar outflow, namely the L1157-B1 shock, at about 0.1 pc from the protostellar cocoon. The detection was obtained…
