Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. III: Hunting for electron-capture supernovae using nebular spectroscopy
Kaustav K. Das, Anders Jerkstrand, Mansi M. Kasliwal +18
Electron-capture supernovae (ECSNe) may arise from ONeMg-core collapse in super-asymptotic giant branch (sAGB) stars near the low-mass core-collapse limit (--\,\Msu…

Emission line models for the lowest mass core-collapse supernovae -- II. 3D NLTE radiative transfer modelling of a neutrino-driven explosion
Bart F. A. van Baal, Anders Jerkstrand, Daniel Kresse +1
The nebular phase of a supernova (SN) occurs several months to years after the explosion, with asymmetries created by the explosion encoded into the line profiles of the emission l…
