Cosmic-Ray Induced Diffusion in Interstellar Ices

open access: yesOpen Astronomy, 2014
Cosmic rays are able to heat interstellar dust grains. This may enhance molecule mobility in icy mantles that have accumulated on the grains in dark cloud cores.

Infrared Spectroscopic and Physical Properties of Methanol Ices—Reconciling the Conflicting Published Band Strengths of an Important Interstellar Solid

open access: yesThe Astrophysical Journal
Infrared spectroscopic observations have established the presence of solid methanol (CH _3 OH) in the interstellar medium and in solar system ices, but the abundance of frozen CH _3 OH cannot be deduced without accurate band strengths, optical constants,

Carbon Dioxide Ices—A Sexagennial Update of Infrared Intensities, Band Shapes, and the Formation and Destruction of Crystalline CO2

open access: yesThe Astrophysical Journal
The infrared (IR) band strengths most often used to quantify laboratory and astronomical spectra of CO _2 ices are now 60 yr old, from a time of slide rules and vacuum-tube technology.
