Determine whether differential ablation explains the double-banded detection-height distribution

Determine whether differential-ablation models reproduce the observed double-banded initial detection-height distribution and whether catalogue-wide height statistics can constrain meteoroid chemical composition.

Background

The PANSY catalogue exhibits two distinct bands in the initial meteor detection-height distribution, and the two bands have different radiant distributions. The paper interprets this structure as potentially arising from differences in meteoroid size, composition, and differential ablation, but notes that these effects cannot yet be disentangled observationally.

The authors identify chemical-ablation modeling as necessary to test whether volatile release, organic pyrolysis, and refractory-metal ablation can reproduce the observed height bands and to assess whether the catalogue can provide constraints on meteoroid composition.
