Analysis
This paper provides detailed observations and analysis of a bright Type Iax supernova, SN 2022eyw. It contributes to our understanding of the explosion mechanisms of these supernovae, which are thought to be caused by the partial deflagration of white dwarfs. The study uses photometric and spectroscopic data, along with spectral modeling, to determine properties like the mass of synthesized nickel, ejecta mass, and kinetic energy. The findings support the pure deflagration model for luminous Iax supernovae.
Key Takeaways
- •SN 2022eyw is a bright Type Iax supernova.
- •Observations support the pure deflagration model for its explosion.
- •The study provides detailed measurements of key properties like nickel mass and ejecta mass.
Reference
“The bolometric light curve indicates a synthesized $^{56}$Ni mass of $0.120\pm0.003~ ext{M}_{\odot}$, with an estimated ejecta mass of $0.79\pm0.09~ ext{M}_{\odot}$ and kinetic energy of $0.19 imes10^{51}$ erg.”
