Ice chemistry that can be unveiled with the JWST: SynthIceSpec, a synthetic spectrum generator to test spectral limits. Solid CO_2 as a dust thermometer and solid CH_3CN detectability in cold cores
A. Taillard, P. Gratier, J. A. Noble +7
As the (JWST) pursues its observing journey, several thousands of icy-grain spectra are expected to be measured and analysed. The inventory of ices in particular, via the observati…
c-C3H2 deuteration towards prestellar and starless cores in the Perseus Molecular Cloud
J. Ferrer Asensio, S. Scibelli, L. Steffes +6
Deuterium fractionation becomes highly efficient in cold, dense cores where CO is frozen out. Cyclopropenylidene (c-C3H2), an early-formed carbon ring, and its deuterated isotopolo…
Fine-tuning the complex organic molecule formation: sulfur and CO ice as regulators of surface chemistry
D. Navarro-Almaida, A. Taillard, A. Fuente +3
Grain-surface chemistry plays a crucial role in the formation of molecules of astrobiological interest, including HS and complex organic molecules (COMs). They are commonly o…
Chemical constraints on the dynamical evolution of the cold core L694
A. Taillard, V. Wakelam, P. Gratier +4
In star-forming regions, molecular cloud history and dynamics set the trend in the chemical composition. Ice formation, in particular, is affected by the evolution of physical cond…
Modelling methanol and hydride formation in the JWST Ice Age era
Izaskun Jiménez-Serra, Andrés MegÃas, Joseph Salaris +19
(Abridged) JWST observations have measured the ice composition toward two highly-extinguished field stars in the Chamaeleon I cloud. The observed extinction excess on the long-wave…
Predicting the detectability of sulphur-bearing molecules in the solid phase with simulated spectra of JWST instruments
A. Taillard, R. MartÃn-Doménech, H. Carrascosa +7
To date, gas phase observations of sulphur in dense interstellar environments have only constrained the molecular carriers of 1% of its predicted cosmic abundance. An additional 5%…
