Mercoledì 8 gennaio alle ore 11:00, la Dr. Ambra Nanni del National Centre For Nuclear Research (Polonia) terrà il seminario dal titolo “Forging cosmic dust: the role of thermally pulsing asymptotic giant branch stars“.

Abstract

Thermally pulsing asymptotic giant branch (TP-AGB) stars are among the Universe’s most prolific dust producers, enriching galaxies with metals partially locked into dust grains. Stellar pulsations drive shock waves that push gas to regions cool enough for dust to form. Once created, these dust grains can be propelled outward as photons impart sufficient momentum to power the stellar wind. Despite their fundamental importance, key questions remain about how these “dust factories” operate—especially the processes governing dust condensation and mass loss. In this talk, I will summarize the insights gained from recent observations of TP-AGB stars and the latest theoretical models, highlighting both the remarkable progress we have made and the critical challenges that lie ahead.
