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…
Infrared spectroscopy of astrophysical ice analogs at oblique angles
Cristóbal González DÃaz, Hector Carrascosa, Guillermo M. Muñoz Caro
In astrochemical exploration, infrared (IR) spectroscopy is vital for understanding the composition and structure of ice in various space environments. This article explores the im…
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 origins of OCS and chemistry of CS2-bearing ice mantles
Rafael Martin-Domenech, Karin I. Ãberg, Guillermo M. Muñoz Caro +3
Understanding the formation of carbonyl sulfide (OCS) in interstellar ices is key to constrain the sulfur chemistry in the interstellar medium (ISM), since it is the only ice S-bea…
Formation and desorption of sulfur chains (HS and S) in cometary ice: effects of ice composition and temperature
H. Carrascosa, G. M. Muñoz Caro, R. MartÃn-Doménech +3
The reservoir of sulfur accounting for sulfur depletion in the gas of dense clouds and circumstellar regions is still unclear. One possibility is the formation of sulfur chains, wh…
Characterization of carbon dioxide on Ganymede and Europa supported by experiments: Effects of temperature, porosity, and mixing with water
L. Schiltz, B. Escribano, G. M. Muñoz Caro +8
The surfaces of icy moons are primarily composed of water ice that can be mixed with other compounds, such as carbon dioxide. The carbon dioxide (CO stretching fundamental ban…
