Charting circumstellar chemistry of carbon-rich asymptotic giant branch stars. III. SiO and SiS abundances
R. Unnikrishnan, E. De Beck, L. -Å. Nyman +9
The present understanding of C-rich AGB chemistry largely relies on observations of the archetypal carbon star IRC+10216. Current molecular abundance estimates for carbon stars are…
The UMIST Database for Astrochemistry 2022
T J Millar, C Walsh, M Van de Sande +1
Detailed astrochemical models are a key component to interpret the observations of interstellar and circumstellar molecules since they allow important physical properties of the ga…
Complex organic molecules along the accretion flow in isolated and externally irradiated protoplanetary disks
Catherine Walsh, Eric Herbst, Hideko Nomura +2
(Abridged) The birth environment of the Sun will have influenced the conditions in the pre-solar nebula, including the attainable chemical complexity, important for prebiotic chemi…
The UMIST database for astrochemistry 2012
D. McElroy, C. Walsh, A. J. Markwick +3
We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new…
CH abundance gradient in TMC-1
Aleksi Suutarinen, Wolf Dietrich Geppert, Jorma Harju +6
We observed the 9-cm Lambda-doubling lines of CH along the dense filament of TMC-1. The CH column densities were compared with the total H2 column densities derived using the 2MASS…
Carbon chemistry in Galactic Bulge Planetary Nebulae
L. Guzman-Ramirez, A. A. Zijlstra, R. Ni Chuimin +4
Galactic Bulge Planetary Nebulae show evidence of mixed chemistry with emission from both silicate dust and PAHs. This mixed chemistry is unlikely to be related to carbon dredge up…
