SOLIS II. Carbon-chain growth in the Solar-type protocluster OMC2-FIR4
F. Fontani, C. Ceccarelli, C. Favre +42
The interstellar delivery of carbon atoms locked into molecules might be one of the key ingredients for the emergence of life. Cyanopolyynes are carbon chains delimited at their tw…
History of the solar-type protostar IRAS16293-2422 as told by the cyanopolyynes
A. A. Jaber, C. Ceccarelli, C. Kahane +9
Cyanopolyynes are chains of carbon atoms with an atom of hydrogen and a CN group on either side. They are detected almost everywhere in the ISM, as well as in comets. In the past,…
Collisional excitation of HC3N by para- and ortho-H2
A. Faure, F. Lique, L. Wiesenfeld
New calculations for rotational excitation of cyanoacetylene by collisions with hydrogen molecules are performed to include the lowest 38 rotational levels of HC3N and kinetic temp…
Collisional excitation of doubly and triply deuterated ammonia NDH and ND by H
F. Daniel, C. Rist, A. Faure +6
The availability of collisional rate coefficients is a prerequisite for an accurate interpretation of astrophysical observations, since the observed media often harbour densities w…
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…
Radiation thermo-chemical models of protoplanetary discs. IV Modelling CO ro-vibrational emission from Herbig Ae discs
Wing-Fai Thi, Inga Kamp, Peter Woitke +3
The carbon monoxide rovibrational emission from discs around Herbig Ae stars and T Tauri stars with strong ultraviolet emissions suggests that fluorescence pumping from the ground…
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…
