Determine whether the SN 1983V dust survives the shocks and contributes to the galactic dust budget

Determine whether the dust surrounding SN 1983V survives interaction with the forward shock and consequently contributes to the overall galactic dust budget.

Background

The analysis favors collisional heating of pre-existing circumstellar dust by a late-time forward shock. Although SN 1983V contains a substantial inferred dust mass, the eventual fate of that dust is not established.

The authors identify continued observations as necessary to determine whether the dust survives the shocks. This question is relevant to assessing whether stripped-envelope supernova progenitors make a meaningful contribution to cosmic and galactic dust reservoirs.

References

Whether this dust survives and contributes to the overall galactic dust budget remains an open question.
