The connection between warm carbon chain chemistry and interstellar irradiation of star-forming cores
Juris Kalvans
Some observations of warm carbon chain chemistry (WCCC) cores indicate that they are often located near the edges of molecular clouds. This finding may suggest that WCCC is promote…
Evaporative cooling of icy interstellar grains II. Key parameters
Juris Kalvāns, Juris Roberts Kalnin
Context. Evaporative (sublimation) cooling of icy interstellar grains occurs when the grains have been suddenly heated by a cosmic-ray (CR) particle or other process. It results in…
Evaporative cooling of icy interstellar grains. I. Basic characterization
Juris Kalvans, Juris Roberts Kalnin
Context. While radiative cooling of interstellar grains is a well-known process, little detail is known about the cooling of grains with an icy mantle that contains volatile adsorb…
Chemical significance of different temperature regimes for cosmic-ray-induced heating of whole interstellar grains
Juris Kalvans, Juris Roberts Kalnin
Cosmic-ray-induced whole-grain heating induces evaporation and other processes that affect the chemistry of interstellar clouds. With recent data on grain heating frequencies as an…
Temperature spectra of interstellar dust grains heated by cosmic-rays II: dark cloud cores
Juris Kalvāns
Cosmic-ray (CR) induced heating of whole interstellar grains is an important desorption mechanism for grain surface molecules in interstellar molecular clouds. This study aims to p…
The efficiency of photodissociation for molecules in interstellar ices
Juris Kalvans
Processing by interstellar photons affects the composition of the icy mantles on interstellar grains. The rate of photodissociation in solids differs from that of molecules in the…
