Depending upon their mass loss history and rotation rates, these stars will end their lives as pulsational pair-instability supernovae producing a great variety of observational transients with total durations ranging from weeks to millennia and luminosities from 10$^{41}$ to over 10$^{44}$ erg s$^{-1}$. No non-rotating model radiates more than $5 \\times 10^{50}$ erg of light or has a kinetic energy exceeding $5 \\times 10^{51}$ erg, but greater energies are possible, in principle, in magnetar-powered explosions which are explored. Many events resemble Type Ibn, Icn, and IIn supernovae, and some potential observational counterparts are mentioned. Some PPISN can exist in a dormant state for extended periods, producing explosions millennia after their first violent pulse. These dormant supernovae contain bright Wolf-Rayet stars, possibly embedded in bright x-ray and radio sources. The relevance of PPISN to supernova impostors like Eta Carinae, to super-luminous supernovae, and to sources of gravitational radiation is discussed. No black holes between 52 and 133 solar masses are expected from stellar evolution in close binaries.","external_url":"https://arxiv.org/abs/1608.08939","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-06-26T23:10:14.164649+00:00","pith_arxiv_id":"1608.08939","created_at":"2026-05-13T21:03:19.856392+00:00","updated_at":"2026-06-26T23:10:14.164649+00:00","title_quality_ok":true,"display_title":"Pulsational Pair-Instability Supernovae","render_title":"Pulsational Pair-Instability Supernovae"},"hub":{"state":{"work_id":"45855cf5-4153-4b90-bcf2-639b8fadac85","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":12,"external_cited_by_count":null,"distinct_field_count":4,"first_pith_cited_at":"2021-08-02T17:09:29+00:00","last_pith_cited_at":"2026-06-20T01:25:30+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-06-28T00:26:42.682759+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":5}],"polarity_counts":[{"context_polarity":"background","n":4},{"context_polarity":"support","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
