Light Curves and Spectra from a Unimodal Core-Collapse SuperNova

Understand

To assess the effectiveness of optical emission as a probe of spatial asymmetry in core-collapse supernovae (CCSNe), we apply the radiative transfer software, \supernu, to a unimodal CCSN model.

• The \snsph\ radiation-hydrodynamics software was used to simulate an asymmetric explosion of a 16 M$_{\odot}$ ZAMS binary star.
• The ejecta has 3.36 M$_{\odot}$ with 0.024 M$_{\odot}$ of radioactive $^{56}$Ni, with unipolar asymmetry along the z-axis.
• For 96 discrete angular views, we find the ratio between maximum and minimum peak total luminosities is $\sim$1.36.
