Analysis
This paper uses radiative transfer modeling to analyze the spectral evolution of Type Iax supernova 2020rea. The key finding is that the supernova's ejecta show stratified, velocity-dependent abundances at early times, transitioning to a more homogeneous composition later. This challenges existing pure deflagration models and suggests a need for further investigation into the origin and spectral properties of Type Iax supernovae.
Key Takeaways
- •Investigates the spectral evolution of Type Iax SN 2020rea using the TARDIS code.
- •Finds stratified, velocity-dependent abundances at early times.
- •Suggests a transition to a more homogeneous composition as the SN evolves.
- •Challenges existing pure deflagration models.
