Dust production by supernovae and massive stars: Dust production by supernovae and massive stars

In this review I will cover the theoretical expectations and the observational evidence as to whether massive stars and their supernovae can form sufficiently large quantities of dust to provide a significant contribution to the dust budgets of galaxies.
A series of papers addressing dust condensation in the ejecta of core-collapse supernovae (CCSNe) have predicted that up to one solar mass...
The large reservoirs of dust observed in some high redshift galaxies have been hypothesised to originate from dust produced by supernovae (SN). Theoretical models predict that core-collapse SN can be efficient dust producers (0.1-1 M$_\odot$) potentially responsible for most of the dust production in the early Universe. Observational evidence for this dust production efficiency is however...
There is still on-going debate as to how much dust has been formed and destroyed by supernovae and supernova remnants. A systematic search for dust in supernova remnants is an effective way to resolve this issue. We search for far-infrared counterparts of 62 known supernova remnants in the Galactic plane (| l |<60○) at 70, 160, 250, 350, and 500µm using the Herschel Infrared Galactic Plane...
The light curve of Type IIn supernovae are dominated by the radiative energy release through the interaction of the supernova blastwave with their dense circumstellar medium (CSM). Specifically, in case of ultraluminous Type IIn supernova SN 2010jl, the spectra show an excess in the IR component as early as a few weeks after the explosion. The IR emission has been attributed by some as...
Core-collapse supernovae (SNe) are considered to play a dual role in the production and destruction of dust in the interstellar media of galaxies. Currently, the subjects of intense investigations are the questions of how much dust SNe form, and how much dust survives SN shocks.
Supernova 1987A is the nearest supernova explosion detected in the last 400 years, and provides a unique...
The discovery of 0.4-0.7M$_\odot$ of dust in the remnant of SN1987A 23 years
after its explosion (Matsuura et al. 2011) demonstrated that supernovae can be
efficient dust factories, but raised many questions. Among them, when did this
dust form? Was it there at early times but previously undiagnosed by
techniques for estimating dust masses, or did it form at later times? In
Wesson et al....
