Redistribution of ices between grain populations in protostellar envelopes. Only the coldest grains get ices
Juris KalvÄns
Context. Matter that falls onto a protoplanetary disk (PPD) from a protostellar envelope is heated before it cools again. This induces sublimation and subsequent re-adsorption of i…

Effects of grain temperature distribution on organic protostellar envelope chemistry
Juris Kalvans, Juris Freimanis
Context. Dust grains in circumstellar envelopes are likely to have a spread-out temperature distribution. Aims. To investigate how trends in temperature distribution between small…
