Photodesorption of H2O, HDO, and D2O ice and its impact on fractionation
Carina Arasa, Jesper Koning, Geert-Jan Kroes +2
The HDO/H2O ratio in interstellar gas is often used to draw conclusions on the origin of water in star-forming regions and on Earth. In cold cores and in the outer regions of proto…
Molecular Dynamics Simulations of CO2 Formation in Interstellar Ices
Carina Arasa, Marc C. van Hemert, Ewine F. van Dishoeck +1
CO2 ice is one of the most abundant components in ice-coated interstellar ices besides H2O and CO, but the most favorable path to CO2 ice is still unclear. Molecular dynamics calcu…
Molecular dynamics simulations of D2O ice photodesorption
C. Arasa, S. Andersson, H. M. Cuppen +2
Molecular dynamics calculations have been performed to study the ultraviolet photodissociation of D2O in an amorphous D2O ice surface at 10-90 K, in order to investigate the influe…
Molecular dynamics simulations of the ice temperature dependence of water ice photodesorption
C. Arasa, S. Andersson, H. M. Cuppen +2
The ultraviolet (UV) photodissociation of amorphous water ice at different ice temperatures is investigated using molecular dynamics (MD) simulations and analytical potentials. Pre…
Molecular dynamics study of photodissociation of water in crystalline and amorphous ice
Stefan Andersson, Ayman Al-Halabi, Geert-Jan Kroes +1
We present results of classical dynamics calculations, performed to study the photodissociation of water in crystalline and amorphous ice surfaces at a surface temperature of 10 K.…
Photodissociation of water in crystalline ice: a molecular dynamics study
Stefan Andersson, Geert-Jan Kroes, Ewine F. van Dishoeck
Ultraviolet irradiation of ice is of great interest for understanding the chemistry in both atmospheric and astrophysical environments. In interstellar space, photodissociation of…
