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…
UV photoprocessing of NH3 ice: photon-induced desorption mechanisms
R. Martin-Domenech, G. A. Cruz-Diaz, G. M. Munoz Caro
Ice mantles detected on the surface of dust grains toward the coldest regions of the interstellar medium can be photoprocessed by the secondary ultraviolet (UV) field present in de…
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…
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…
The QUEST RR Lyrae Survey: III. The Low Galactic Latitude Catalogue
Cecilia Mateu, A. Katherina Vivas, Juan José Downes +3
We present results for the QUEST RR Lyrae Survey at low galactic latitude, conducted entirely with observations obtained with the QUEST mosaic camera and the 1.0/1.5m Jürgen Stock…
