Long-Term Survival of Dust Grains Produced After Stellar Eruptions
Massive stars experience periods of intense instability in their late stages of evolution, just before their final core-collapse. These periods are characterized by presenting very high mass loss rates during some years or decades, known as stellar outbursts. When these outbursts occur, copious amou...

| Sumario: | Massive stars experience periods of intense instability in their late stages of evolution, just before their final core-collapse. These periods are characterized by presenting very high mass loss rates during some years or decades, known as stellar outbursts. When these outbursts occur, copious amounts of dust are formed from the erupted mass, which can contribute to the enrichment of the interstellar medium with dust. However, the survival of these dust grains is threatened by the powerful shock waves driven by the eventual explosion of the progenitor star as a supernova. Therefore, in this work, hydrodynamic modeling techniques are used to investigate the effects of the supernova explosion on the recently created dust grains, in order to determine whether complete or partial dust destruction occurs. |
