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.

Nonthermal Ionization of Kilonova Ejecta: Observable Impacts

The Astrophysical Journal
The characteristic rapid rise and decline at optical wavelengths of a kilonova is the product of the low ejecta mass (≲0.05 M _⊙ ) and high ejecta velocity (≳0.1 c ). We show that, even at very early times (≲2 days), regions of ejecta fall below critical

DART Impact Ejecta Plume Evolution: Implications for Dimorphos

The Planetary Science Journal
The NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...
