Low-luminosity type IIP supermnovae: SN 2005cs and SN 2020cxd as very low-energy iron core-collapse explosions
Low-luminosity type IIP supermnovae: SN 2005cs and SN 2020cxd as very low-energy iron core-collapse explosions
SN 2020cxd is a representative of the family of low-energy, underluminous Type IIP supernovae (SNe), whose observations and analysis were recently reported by Yang et al. (2021). Here we re-evaluate the observational data for the diagnostic SN properties by employing the hydrodynamic explosion model of a 9 MSun red supergiant …
