1100 days in the life of the supernova 2018ibb
Stars with zero-age main sequence masses between 140 and 260 M ⊙ are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce up to several tens of solar masses of radioactive nickel, resulting in luminous transients similar to some superluminous supernovae (SLSNe). Yet, no unambiguous …
