Metallicity differences between Type IIP and stripped-envelope supernova environments
R. Ganss, J. L. Pledger, A. E. Sansom +3
This work presents measurements of local HII environment metallicities of core-collapse supernovae (SNe) in hosts with redshifts up to z0.025. 139 SNe environments were obser…

Possible detection of the progenitor of the Type II supernova SN2023ixf
Joanne L. Pledger, Michael M. Shara
Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is import…
