20 entries in the Supernovae compendium.
Calcium-rich supernovaFaint supernovae rich in calcium, often found far from galaxies.Failed supernovaA star collapses into a black hole without a supernova flash.Pair-instability supernovaA supernova that completely disrupts the star, leaving no remnant.Diffuse supernova neutrino backgroundCumulative neutrino flux from all core-collapse supernovae in the universe.History of supernova observationFrom ancient guest stars to modern cosmic distance probes.Katzman Automatic Imaging TelescopeRobotic telescope at Lick Observatory for supernova discovery.M31-2014-DS1A massive star that collapsed directly into a black hole.MeigetsukiHeian-Kamakura diary recording astronomical phenomena and court life.Near-Earth supernovaA stellar explosion close enough to impact Earth's biosphere.P-nucleiProton-rich isotopes not made by s- or r-process nucleosynthesis.P-processNucleosynthesis process for neutron-deficient isotopes via proton capture.Pulsational pair-instability supernovaA stellar eruption that sheds mass, avoiding full disruption.R-processNuclear reactions creating half of heavy elements beyond iron.SN 1952GSupernova of unknown type discovered in NGC 5668 in 1952.SN 1969HType I supernova discovered by Anthony Fairall in 1969.SN 1976BSupernova in a ram-pressure-stripped Virgo Cluster galaxy.SN 2021yfjFirst candidate Type Ien supernova, 2.2 billion light years away.SuperNova Early Warning SystemNeutrino-based early warning for galactic supernovae.Supernova neutrinosNeutrinos from core-collapse supernovae carry away most of the star's energy.Type Ia supernovaA standard candle supernova from white dwarf accretion or merger.
