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…
The edge-on disk Tau042021: icy grains at high altitudes and a wind containing astronomical PAHs
E. Dartois, J. A. Noble, M. K. McClure +9
Spectra of the nearly edge-on protoplanetary disks observed with the JWST have shown ice absorption bands of varying optical depths and peculiar profiles, challenging radiative tra…
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%…
Ice inventory towards the protostar Ced 110 IRS4 observed with the James Webb Space Telescope. Results from the ERS Ice Age program
W. R. M. Rocha, M. K. McClure, J. A. Sturm +37
This work focuses on the ice features toward the binary protostellar system Ced 110 IRS 4A and 4B, and observed with JWST as part of the Early Release Science Ice Age collaboration…
Observation of a core-excited dipole-bound state 1 eV above the electron detachment threshold in cryogenically cooled acetylacetonate
Rafael A Jara-Toro, MartÃn Taccone, Jordan Dezalay +3
Dipole-bound states in anions exist when a polar neutral core binds an electron in a diffuse orbital through charge--dipole interaction. Electronically excited polar neutral cores…
