Core-collapse supernovae in low-metallicity environments and future all-sky transient surveys

Core-collapse supernovae in low-metallicity environments and future all-sky transient surveys

Aims: Massive stars in low-metallicity environments may produce exotic explosions such as long-duration gamma-ray bursts and pair-instability supernovae when they die as core-collapse supernovae (CCSNe). Here we determine the feasibility of searching for these CCSNe in metal-poor dwarf galaxies using various survey strategies. Methods: We determine oxygen abundances and star-formation …
