Dependence of Dust Formation on the Supernova Explosion

TL;DR

This study models dust formation in core-collapse supernovae, revealing how explosion energy, progenitor mass, and nuclear burning influence dust properties and production efficiency across different metallicities.

Contribution

It provides a comprehensive analysis of dust formation dependencies on supernova explosion parameters using detailed hydrodynamics and nucleation models.

Findings

Higher explosion energies cause earlier dust formation and smaller grains.

Nuclear burning enhances silicate dust production.

Dust formation efficiency varies with metallicity.

Abstract

We investigate the properties, composition, and dynamics of dust formation and growth for a diverse set of core-collapse supernovae (CCSNe), varying the progenitor mass, explosion energy, and engine type. These explosions are evolved with a 1-D Lagrangian hydrodynamics code out to several hundred days to model the ejecta as it expands and cools. A multigrain dust nucleation and growth model is applied to these results. We find that higher explosion energies lead to an earlier onset of dust formation, smaller grain sizes, and larger silicate abundances. Further, we see that nuclear burning during the explosion leads to enhanced formation of silicate dust. Finally, we build composite models from our suite to predict the efficiency of CCSNe dust production as a function of metallicity.
