Characterize the contributions of distinct dust populations to the apparent dust-mass trend

Characterize the extent to which newly formed dust, pre-existing dust, and combinations of these populations contribute to the apparent increase in measured supernova dust mass with time.

Background

The compiled supernova sample contains objects in which the dust is interpreted as newly formed, pre-existing, or a mixture of both. The paper emphasizes that SN 1983V likely contains pre-existing dust, whereas other supernovae in the comparison sample may contain newly formed dust.

Because the sample is limited and heterogeneous, the relative influence of these dust populations on the apparent temporal trend remains unresolved. Additional observations using consistent methods are needed to distinguish a genuine physical evolution from population and observational effects.

References

To what degree these dust populations affect or contribute to this apparent trend remains inconclusive with the current limit in sample size and breadth.
