Ortho-to-para ratio of NH2. Herschel-HIFI observations of ortho- and para-NH2 rotational transitions towards W31C, W49N, W51 and G34.3+0.1
C. M. Persson, A. O. H. Olofsson, R. Le Gal +10
We have used the Herschel-HIFI instrument to observe both nuclear spin symmetries of amidogen (NH2) towards the high-mass star-forming regions W31C (G10.6-0.4), W49N (G43.2-0.1), W…
Stratified NH and ND emission in the prestellar core 16293E in L1689N
A. Bacmann, F. Daniel, P. Caselli +6
High degrees of deuterium fractionation are commonly found in cold prestellar cores and in the envelopes around young protostars. As it brings strong constraints to chemical models…
Jet multiplicity in the proto-binary system NGC1333-IRAS4A. The detailed CALYPSO IRAM-PdBI view
G. Santangelo, C. Codella, S. Cabrit +10
Owing to the paucity of sub-arcsecond (sub)mm observations required to probe the innermost regions of newly forming protostars, several fundamental questions are still being debate…
Mapping CO Gas in the GG Tauri A Triple System with 50 AU Spatial Resolution
Ya-Wen Tang, Anne Dutrey, Stephane Guilloteau +11
We aim to unveil the observational imprint of physical mechanisms that govern planetary formation in the young, multiple system GG Tau A. We present ALMA observations of CO…
Electron-impact excitation of diatomic hydride cations I: HeH, CH, ArH
James R. Hamilton, Alexandre Faure, Jonathan Tennyson
{\bf R}-matrix calculations combined with the adiabatic nuclei approximation are used to compute electron-impact rotiational excitation rates for three closed-shell diatomic cation…
Multivariate Approaches to Classification in Extragalactic Astronomy
Didier Fraix-Burnet, Marc Thuillard, Asis Kumar Chattopadhyay
Clustering objects into synthetic groups is a natural activity of any science. Astrophysics is not an exception and is now facing a deluge of data. For galaxies, the one-century ol…
Gas phase formation of the prebiotic molecule formamide: insights from new quantum computations
V. Barone, C. Latouche, D. Skouteris +4
New insights into the formation of interstellar formamide, a species of great relevance in prebiotic chemistry, are provided by electronic structure and kinetic calculations for th…
Hyperfine transitions of 13CN from pre-protostellar sources
David Flower, Pierre Hily-Blant
Recent quantum mechanical calculations of rate coefficients for collisional transfer of population between the hyperfine states of 13CN enable their population densities to be dete…
Stellar populations in Centauri: a multivariate analysis
Didier Fraix-Burnet, E. Davoust
We have performed multivariate statistical analyses of photometric and chemical abundance parameters of three large samples of stars in the globular cluster Centauri. The stati…
The jet and the disk of the HH 212 low-mass protostar imaged by ALMA: SO and SO2 emission
L. Podio, C. Codella, F. Gueth +8
To investigate the disk formation and jet launch in protostars is crucial to comprehend the earliest stages of star and planet formation. We aim to constrain the properties of the…
Discovery of SiCSi in IRC+10216: A missing link between gas and dust carriers of SiC bonds
J. Cernicharo, M. C. McCarthy, C. A. Gottlieb +13
We report the discovery in space of a disilicon species, SiCSi, from observations between 80 and 350 GHz with the IRAM 30m radio telescope. Owing to the close coordination between…
The existence of warm and optically thick dissipative coronae above accretion disks
A. Rozanska, J. Malzac, R. Belmont +2
In the past years, several observations of AGN and X-ray binaries have suggested the existence of a warm T around 0.5-1 keV and optically thick, τ~ 10-20, corona covering the inner…
The soft and hard X-rays thermal emission from star cluster winds with a supernova explosion
A. Castellanos-Ramirez, A. Rodriguez-Gonzalez, A. Esquivel +3
Massive young star clusters contain dozens or hundreds of massive stars that inject mechanical energy in the form of winds and supernova explosions, producing an outflow which expa…
ALMA Long Baseline Observations of the Strongly Lensed Submillimeter Galaxy HATLAS J090311.6+003906 at z=3.042
ALMA Partnership, C. Vlahakis, T. R. Hunter +78
We present initial results of very high resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the =3.042 gravitationally lensed galaxy HATLAS J090311.6+…
Very Large Telescope observations of Gomez's Hamburger: Insights into a young protoplanet candidate
O. Berne, A. Fuente, E. Pantin +8
Planets are thought to form in the gas and dust disks around young stars. In particular, it has been proposed that giant planets can form through the gravitational instability of m…
The 2014 KIDA network for interstellar chemistry
V. Wakelam, J. -C. Loison, E. Herbst +21
Chemical models used to study the chemical composition of the gas and the ices in the interstellar medium are based on a network of chemical reactions and associated rate coefficie…
Impacts of pure shocks in the BHR71 bipolar outflow
Antoine Gusdorf, Denise Riquelme, Sibylle Anderl +10
During the formation of a star, material is ejected along powerful jets that impact the ambient material. This outflow regulates star formation by e.g. inducing turbulence and heat…
