Collisional excitation of cyclopentadiene by helium. A complete set of rate coefficients and astrophysical applications
Sándor Demes, François Lique, Marcelino Agúndez +1
Complex organic molecules, including large cyclic species, are prevalent in interstellar space and play a key role in various astrochemical processes. Cyclopentadiene (c-C5H6) is a…
Laboratory spectroscopy, theoretical characterization, and astronomical search for syn-propenethial (CH2CHCHS)
Germán Molpeceres, Carlos Cabezas, Marcelino Agúndez +5
We report the laboratory characterization of the higher-energy isomer of propenethial, syn-CH2CHCHS. While the lower-energy isomer, anti-CH2CHCHS, was detected in the interstellar…
The formation radius of HCN in O-rich asymptotic giant branch stars
L. Marinho, J. P. Fonfría, M. Agúndez +3
Molecules detected in circumstellar envelopes around asymptotic giant branch (AGB) stars are generally well explained in terms of formation under chemical equilibrium in the stella…
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…
TMC-1: probing the onset of chemical complexity in space
Marcelino Agundez, Jose Cernicharo
In recent years, the obsessive interest in the observation of TMC-1 has brought a boost in our knowledge of the chemistry of cold dark clouds. The number of molecules detected in t…
Ion-molecule routes towards cycles in TMC-1. An automated study of the C2H4 + CH2CCH+ reaction
María Mallo, Marcelino Agúndez, Carlos Cabezas +3
Cyclopentadiene (c-C5H6) is considered a key molecule in the formation of polycyclic aromatic hydrocarbons (PAHs) in the interstellar medium (ISM). The synthesis of PAHs from simpl…
