Since the circumstellar medium is created by the mass lost from the progenitor star, it carries tell-tale signatures of the progenitor. Consequently, observations and modeling of radiation produced by the interaction in various types of supernovae have provided valuable insights into their progenitors. Detailed studies have shown that the interaction in supernovae begins and sustains over various timescales and lengthscales, with differing mass-loss rates in distinct sub-classes. This reveals diverse progenitor histories for these stellar explosions. This review paper summarizes various supernova subtypes, linking them to stellar death pathways, and presents an updated supernova classification diagram. We then present a multi-wavelength study of circumstellar interaction in different supernova classes. We also present unpublished X-ray as well as radio observations of a type IIn supernova, SN 2010jl, which allow us to extend its circumstellar interaction studies to about 7 years post-explosion. The new data indicates that the extreme mass-loss rate (similar to 0.1 M circle dot yr-1) in SN 2010jl, reported by Chandra et al. commenced within the last 300 years before the explosion. We summarize the current status of the field and argue that via detailed studies of the circumstellar interaction, a.k.a. "Time Machine" technique, one of the big mysteries of stellar evolution, i.e., mapping supernovae progenitors to their explosive outcomes can be solved. 2025 true true true false false GOLD 2026-05-27 false https://www.mdpi.com/journal/universe 0 0 0 0 0 0 0 0 0 0 0 0 12 12 Q2 false false false false 2026-03-03T11:43:21.837+0000 17 37 0 1 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 128744953 /api/authorship/128744953 1 1.0 true false true Chandra Poonam true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 30261291 /api/publicationidentifier/30261291 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.3390/universe11110363 https://doi.org/10.3390/universe11110363 false true PublicationIdentifier 30261292 /api/publicationidentifier/30261292 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001624685500001 https://www.webofscience.com/wos/woscc/full-record/001624685500001 false true PublicationIdentifier 30415225 /api/publicationidentifier/30415225 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105023094594 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105023094594 false true Keyword 1001242 /api/keyword/1001242 true 1001242 true Keyword 1091452 /api/keyword/1091452 true 1091452 true Keyword 1091470 /api/keyword/1091470 true 1091470 true Keyword 1091479 /api/keyword/1091479 true 1091479 true Keyword 1104055 /api/keyword/1104055 true 1104055 true Keyword 1139855 /api/keyword/1139855 true 1139855 true Keyword 1150489 /api/keyword/1150489 true 1150489 true Keyword 1188217 /api/keyword/1188217 true 1188217 true Keyword 1256524 /api/keyword/1256524 true 1256524 true Keyword 1284748 /api/keyword/1284748 true 1284748 true Keyword 1493283 /api/keyword/1493283 true true Keyword 2396163 /api/keyword/2396163 true true Keyword 2565493 /api/keyword/2565493 true true Keyword 3000931 /api/keyword/3000931 true true Keyword 3941062 /api/keyword/3941062 true true SjrRating 11614168 /api/sjrrating/11614168 85 0.49 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 3101 /api/classificationexternal/3101 true 3101 true Q2 DIRECT true true /api/publication/36469641 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" >Chandra Poonam ✉ </span> </div> </div> <div class="title"><a href="/gui2/?mode=browse&params=publication;36469641" target="_blank">Multiwavelength View of Circumstellar Interaction in Supernovae</a></div> <div> <span class="journal-title">UNIVERSE</span> <span class="journal-issn">( <a target="_blank" href="https://portal.issn.org/resource/ISSN/2218-1997">2218-1997</a>)</span>: <span class="journal-volume">11</span> <span class="journal-issue">11</span> <span class="page"> Paper 363. 45 p. </span> <span class="year">(2025)</span> </div> <div class="pub-footer"> <span class="language" xmlns="http://www.w3.org/1999/html">Nyelv: Angol | </span> <span class="identifiers"> <span class="id identifier oa_none" title="none"> <a style="color:blue" title="10.3390/universe11110363" target="_blank" href="https://doi.org/10.3390/universe11110363"> DOI </a> </span> <span class="id identifier oa_none" title="none"> <a style="color:blue" title="001624685500001" target="_blank" href="https://www.webofscience.com/wos/woscc/full-record/001624685500001"> WoS </a> </span> <span class="id identifier oa_none" title="none"> <a style="color:blue" title="105023094594" target="_blank" href="http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105023094594"> Scopus </a> </span> </span> <div class="publication-citation"> <a target="_blank" href="/api/publication?cond=citations.related;eq;36469641&sort=publishedYear,desc&sort=title"> Idézett közlemények száma: 12 </a> </div> <div class="mtid"><span class="long-pub-mtid">Közlemény: 36469641</span> | <span class="status-data status-VALIDATED"> Egyeztetett </span> Idéző | <span class="type-subtype">Folyóiratcikk ( Összefoglaló cikk ) </span> | <span class="pub-category">Tudományos</span> | <span class="publication-sourceOfData">WOS TAGGED</span> </div> <div class="lastModified">Utolsó módosítás: 2025.12.19. 17:54 Szuper Admin (admin) </div> <pre class="comment" style="margin-top: 0;
