Evolution of Chemistry in the envelope of HOt corinoS (ECHOS). III. Sulphur chemistry in the Class 0 objects HH 212 and NGC 1333 IRAS 4A
P. Fernández-Ruiz, A. Fuente, G. Esplugues +7
Our goal is to find chemical diagnostics to determine the physical conditions in protostellar envelopes and help establish the development of matter during the formation of a low-m…
Chemical study of two starless cores in the B213/L1495 filament
L. Moral-Almansa, A. Fuente, M. RodrÃguez-Baras +7
The chemical evolution of pre-stellar cores during their transition to a protostellar stage is not yet fully understood. Detailed chemical characterizations of these sources are ne…
A quest for sulfur-bearing refractory species. Identification of CaS in the interstellar medium
A. Tasa-Chaveli, Ã. Sánchez-Monge, A. Fuente +10
The recent detection of refractory molecules in massive star-forming regions provides a means of probing the innermost regions of disks around massive stars. These detections also…
Gas-phase Elemental abundances in Molecular cloudS (GEMS) XI. The evolution of HCN, HNC, and N2H+ isotopic ratios in starless cores
A. Tasa-Chaveli, A. Fuente, G. Esplugues +5
Isotopic ratios have been used as chemical diagnostics to investigate the origin of the material in the Solar System. We have determined the HCN, HNC, and N2H+ isotopic ratios and…
Evolution of Chemistry in the envelope of HOt CorinoS (ECHOS) II. The puzzling chemistry of isomers as revealed by the HNCS/HSCN ratio
G. Esplugues, M. RodrÃguez-Baras, D. Navarro-Almaida +8
The observational detection of some metastable isomers in the interstellar medium with abundances comparable to those of the most stable isomer, or even when the stable isomer is n…
Gas phase Elemental abundances in Molecular cloudS (GEMS). X. Observational effects of turbulence on the chemistry of molecular clouds
L. Beitia-Antero, A. Fuente, D. Navarro-Almaida +12
(Abridged) We explore the chemistry of the most abundant C, O, S, and N bearing species in molecular clouds, in the context of the IRAM 30 m Large Programme Gas phase Elemental abu…
