Effective supernova dust yields from rotating and nonrotating stellar progenitors

Q: What does this research mean for the field?

Supernovae can enrich the interstellar medium with carbonaceous grains ranging in size from approximately 1 μm to 100 μm, despite the destructive impact of the reverse shock. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To quantify the mass, composition, and size distribution of dust remaining after a supernova's reverse shock affects ejecta.
Analyzed a grid of supernova models with progenitor masses from 13 to 120 solar masses and metallicities from -3 to 0.
Considered both rotating and nonrotating progenitor stars, examining initial velocities of 0 and 300 km/s.
Studied the impact of different interstellar medium densities on dust survival before and after reverse shock.
Larger grains (≥ 10 μm) are more resistant to destruction by the reverse shock.
Maximum surviving dust mass from nonrotating progenitors is approximately 0.02 solar masses, released by a 120 solar mass progenitor.
Rotating progenitors show a maximum surviving mass fraction of about 5%, equating to around 0.03 solar masses of dust.
