On The Photodesorption of CO Ice Analogues: The Formation of Atomic C in The Ice and the Effect of The VUV Emission Spectrume
N. -E. Sie, G. M. Muñoz Caro, Z. -H. Huang +3
CO ice has a phase transition at 35 K when its structure changes from amorphous to crystalline. Using Reflection absorption Infrared Spectroscopy (RAIRS), Öberg et al. observed…
Desorption Kinetics and Binding Energies of Small Hydrocarbons
Aida Behmard, Edith C. Fayolle, Dawn M. Graninger +5
Small hydrocarbons are an important organic reservoir in protostellar and protoplanetary environments. Constraints on desorption temperatures and binding energies of such hydrocarb…
New measurements on water ice photodesorption and product formation under ultraviolet irradiation
Gustavo A. Cruz-Diaz, Rafael Martín-Doménech, Elena Moreno +2
The photodesorption of icy grain mantles has been claimed to be responsible for the abundance of gas-phase molecules toward cold regions. Being water a ubiquitous molecule, it is c…
Detection of methylisocyanate (CH3NCO) in a solar-type protostar
R. Martín-Doménech, V. Rivilla, I. Jiménez-Serra +3
We report the detection of the prebiotic molecule CH3NCO in a solar-type protostar, IRAS16293-2422 B. A significant abundance of this species on the surface of the comet 67P/Churyu…
Vacuum ultraviolet photolysis of hydrogenated amorphous carbons. III. Diffusion of photo-produced H2 as a function of temperature
Rafael Martín-Doménech, Emmanuel Dartois, Guillermo M. Muñoz Caro
Hydrogenated amorphous carbon (a-C:H) has been proposed as one of the carbonaceous solids detected in the interstellar medium. Energetic processing of the a-C:H particles leads to…
The negligible photodesorption of methanol ice and the active photon-induced desorption of its irradiation products
Gustavo A. Cruz-Diaz, Rafael Martín-Doménech, Guillermo M. Muñoz Caro +1
Methanol is a common component of interstellar and circumstellar ice mantles and is often used as an evolution indicator in star-forming regions. The observations of gas-phase meth…
Study of the photon-induced formation and subsequent desorption of CH3 OH and H2 CO in interstellar ice analogs
R. Martín-Doménech, G. M. Muñoz Caro, G. A. Cruz-Díaz
Methanol and formaldehyde are two simple organic molecules that are ubiquitously detected in the interstellar medium. An origin in the solid phase and a subsequent nonthermal desor…
The sulfur depletion problem: upper limits on the H2S2, HS2, and S2 gas-phase abundances toward the low-mass warm core IRAS16293-2422
R. Martín-Doménech, I. Jiménez-Serra, G. M. Muñoz Caro +5
A fraction of the missing sulfur in dense clouds and circumstellar regions could be in the form of three species not yet de- tected in the interstellar medium: H2S2, HS2, and S2 ac…
UV photoprocessing of CO2 ice: a complete quantification of photochemistry and photon-induced desorption processes
R. Martín-Doménech, J. Manzano-Santamaría, G. M. Muñoz Caro +4
Ice mantles that formed on top of dust grains are photoprocessed by the secondary ultraviolet (UV) field in cold and dense molecular clouds. UV photons induce photochemistry and de…
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…
