Online Meeting
Platfotm: Zoom
Time zone: CEST - Central European Summer Time (Stockholm time)
Scientific rationale
The production and processing of cosmic dust is, to a very high degree, related to supernovae (SNe) arising from massive stars. From the explosion event, to the nebular phase, to the remnant stage, we see nucleation, accretional growth, sputtering, sublimation, fragmentation, and several other processes taking place. Dust grains found in the interstellar medium (ISM) are believed to have formed in SNe and evolved stars and are then further processed and grow in the ISM. SNe play a pivotal role in inducing dust processing as SN shock fronts propagate through the ISM. To what extent this leads to a net destruction of dust material is debated and the net production of dust associated with SN events remains uncertain.
This online mini-workshop aims at bringing together experts in SNe and their evolution and interstellar dust to discuss the role that SNe play in the cosmic dust cycle. Particular emphasis will be put on dynamics; SN blast waves, driving of ISM turbulence, and the transport of dust grains.
