SUMMARY:Pyroclastic Blowout: Dust Survival in Isolated versus Clustered Sup
 ernovae
DESCRIPTION:Pyroclastic Blowout: Dust Survival in Isolated versus Clustered
  Supernovae\nDr. Sergio Martínez-González\n\nFollowing the current debat
 e on the fate of SN-condensed dust grains, I  will present a set of three-
 dimensional hydrodynamical simulations of  the interaction of dusty supern
 ova remnants (SNRs) with the shocked  winds of neighboring massive stars w
 ithin young massive stellar clusters  (SSCs). As a comparison, I will disc
 uss the evolution of supernova  remnants in the diffuse ISM with constant 
 density. Since the  hydrodynamics of SNRs is intimately related to the pro
 perties of their  immediate environment, the lifecycle of dust grains in S
 NRs within SSCs  is radically different from that in the diffuse ISM. More
 over,  off-centered SNRs evolving in the steep density gradient establishe
 d due  to a star cluster wind experience a blowout phase: shell fragmentat
 ion  due to protruding Rayleigh-Taylor instabilities and the venting of SN
   ejecta. The main finding is that clustered SN explosions will cause a  n
 et increase in the amount of dust in the surroundings of young massive  st
 ellar clusters.
