[astro-ph.GA] In the Central Molecular Zone (CMZ), shocks play a key role in triggering star formation and driving chemical enrichment. The Sgr B2 complex is a prime template, hosting massive […]

Redistribution of Ices Between Grain Populations in Protostellar Envelopes. Only the Coldest Grains Get Ices
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 ices that accumulated during […]
