Impact of Pulsar and Fallback Sources on Multifrequency Kilonova Models

Understand

We explore the impact of pulsar electromagnetic dipole and fallback accretion emission on the luminosity of a suite of kilonova models.

• The pulsar models are varied over pulsar magnetic field strength, pulsar lifetime, ejecta mass, and elemental abundances; the fallback models are varied over fallback accretion rate and ejecta mass.
• For the abundances, we use Fe and Nd as representatives of the wind and dynamical ejecta, respectively.
• We simulate radiative transfer in the ejecta in either 1D spherical or 2D cylindrical spatial geometry.
