Discovery of sulfur oxides in the ejecta of a B[e] supergiant
C. Bordiu, J. Ricardo Rizzo, D. Navarro-Almaida +12
B[e] supergiants represent a rare class of luminous, evolved massive stars surrounded by dusty circumstellar disks. Since their intense UV fields were long thought to sterilize the…
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…
First Detection of CH3OD in Prestellar Cores
Beatrice M. Kulterer, Asunción Fuente, Maria N. Drozdovskaya +6
The isotopic ratios of deuterated methanol derived around protostars are commonly used to infer the physical conditions under which they formed in the earlier prestellar stage. How…
Measuring metal sulfides in interstellar dust with PRIMA
Izaskun Jiménez-Serra, Shaoshan Zeng, Yao-Lun Yang +5
Sulfur is known to undergo severe depletion when moving from diffuse clouds to the denser regimes of the interstellar medium in molecular clouds. The form in which sulfur gets depl…
Photodesorption of SO2 and SO from UV-irradiated SO2 ices
Rafael MartÃn-Doménech, Bruno Escribano, David Navarro-Almaida +4
The detection of high gas-phase abundances of SO2 and SO in the cold envelope of an intermediate mass protostar suggests that these molecules might form on icy dust grains and subs…
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%…
