The Significant Role of Hydrogen in the Formation of Silicon Carbide in Evolved Stars
Guillermo Tajuelo-Castilla, Gonzalo Santoro, Lidia Martínez +13
Cosmic dust is mainly formed in the atmospheres of evolved stars. In carbon rich stars, amorphous carbon along with silicon carbide are the main constituents of dust grains yet the…
Infrared spectra of solid indene pure and in water ice. Implications for observed IR absorptions in TMC-1
Belén Maté, Isabel Tanarro, Vicente Timón +2
Experimental and theoretical infrared spectra, between 4000-500 cm (2.5-20 microns), and infrared band strengths of two solid phases of indene, amorphous and crystalline, ar…
2-aminooxazole in astrophysical environments: IR spectra and destruction cross sections for energetic processing
Belén Maté, Ricardo Carrasco-Herrera, Vicente Timón +6
2-aminooxazole (2AO), a N-heterocyclic molecule, has been proposed as an intermediate in prebiotic syntheses. It has been demonstrated that it can be synthesized from small molecul…
Silicon and hydrogen chemistry under laboratory conditions mimicking the atmosphere of evolved stars
Mario Accolla, Gonzalo Santoro, Pablo Merino +10
Silicon is present in interstellar dust grains, meteorites and asteroids, and to date thirteen silicon-bearing molecules have been detected in the gas-phase towards late-type stars…
The chemistry of cosmic dust analogues from C, C, and CH in C-rich circumstellar envelopes
Gonzalo Santoro, Lidia Martínez, Koen Lauwaet +13
Interstellar carbonaceous dust is mainly formed in the innermost regions of circumstellar envelopes around carbon-rich asymptotic giant branch (AGB) stars. In these highly chemical…
Using radio astronomical receivers for molecular spectroscopic characterization in astrochemical laboratory simulations: A proof of concept
I. Tanarro, B. Alemán, P. de Vicente +26
We present a proof of concept on the coupling of radio astronomical receivers and spectrometers with chemical reactorsand the performances of the resulting setup for spectroscopy a…
The high resolution infrared spectrum of HCl
José L. Doménech, Brian J. Drouin, José Cernicharo +2
The chloroniumyl cation, HCl, has been recently identified in space from Herschel's spectra. A joint analysis of extensive vis-UV spectroscopy emission data together with a few…
UV photoprocessing of CO2 ice: a complete quantification of photochemistry and photon-induced desorption processes
R. Martín-Doménech, J. Manzano-Santamaría, G. M. Muñoz Caro +4
Ice mantles that formed on top of dust grains are photoprocessed by the secondary ultraviolet (UV) field in cold and dense molecular clouds. UV photons induce photochemistry and de…
Improved determination of the 1(0)-0(0) rotational frequency of NH3D+ from the high resolution spectrum of the v4 infrared band
J. L. Doménech, M. Cueto, V. J. Herrero +4
The high resolution spectrum of the v4 band of NH3D+ has been measured by difference frequency IR laser spectroscopy in a multipass hollow cathode discharge cell. From the set of m…
Detection of the Ammonium Ion in Space
J. Cernicharo, B. Tercero, A. Fuente +9
We report on the detection of a narrow feature at 262816.73 MHz towards Orion and the cold prestellar core B1-bS, that we attribute to the 1(0)-0(0) line of the deuterated Ammonium…
