Investigation of HNCO isomers formation in ice mantles by UV and thermal processing: an experimental approach
A. Jiménez-Escobar, B. M. Giuliano, G. M. Muñoz Caro +2
Current gas phase models do not account for the abundances of HNCO isomers detected in various environments, suggesting a formation in icy grain mantles. We attempted to study a fo…
Interstellar ice analogs: band strengths of HO, CO, CHOH, and NH in the far-infrared region
B. M. Giuliano, R. M. Escribano, R. Martín-Doménech +2
We measure the band strengths in the far-infrared region of interstellar ice analogs of astrophysically relevant species, such as HO, CO, CHOH, and NH, deposited at…
Thermal desorption of circumstellar and cometary ice analogs
Rafael Martín-Doménech, Guillermo M. Muñoz Caro, Juan Bueno +1
Thermal annealing of interstellar ices takes place in several stages of star formation. Knowledge of this process comes from a combination of astronomical observations and laborato…
Vacuum-UV absorption spectroscopy of interstellar ice analogues. III. Isotopic effects
G. A. Cruz-Diaz, G. M. Muñoz Caro, Y. -J. Chen
This paper reports the first measurements of solid-phase vacuum-ultraviolet (VUV) absorption cross-sections of heavy isotopologues present in icy dust grain mantles of dense inters…
Vacuum-UV spectroscopy of interstellar ice analogs. II. Absorption cross-sections of nonpolar ice molecules
G. A. Cruz-Diaz, G. M. Muñoz Caro, Y. -J. Chen +1
Dust grains in cold circumstellar regions and dark-cloud interiors at 10-20 K are covered by ice mantles. A nonthermal desorption mechanism is invoked to explain the presence of ga…
Vacuum-UV spectroscopy of interstellar ice analogs. I. Absorption cross-sections of polar-ice molecules
G. A. Cruz-Diaz, G. M. Munoz Caro, Y. -J. Chen +1
The VUV absorption cross sections of most molecular solids present in interstellar ice mantles with the exception of H2O, NH3, and CO2 have not been reported yet. Models of ice pho…
Comparison of UV and high-energy ion irradiation of methanol:ammonia ice
G. M. Munoz Caro, E. Dartois, P. Boduch +3
The main goal of this work is to compare the effects induced in ices of astrophysical relevance by high-energy ions, simulating cosmic rays, and by vacuum ultraviolet (UV) photons.…
