Contemporaneous formation of self-secondaries and layered ejecta deposits on Mars

Communications Earth & Environment
Self-secondaries are secondary craters formed in cogenetic ejecta deposits. Bearing important information on cratering mechanics and the applicability of remote age-determination technique using crater statistics, the spatial distribution of self ...

Minimum velocity for impact ejecta to form secondaries on terrestrial bodies

Communications Earth & Environment
The minimum velocity (v) for impact ejecta to form secondary craters (secondaries) remains enigmatic, but it is a crucial parameter in untangling the fate of impact ejecta on planetary surfaces.

The First Day of a Type Ia Supernova from a Double-degenerate Binary

The Astrophysical Journal
Supernovae in binary star systems involve a hydrodynamical interaction between the ejecta and a binary companion. This collision results in shock heating and a modified density structure for the ejecta, both of which affect the light curve.
