Regions rich in red dwarf stars were selected: the area around Orion Trapezium, and the stellar cluster of Pleiades have been chosen to ensure efficiency of observations. The objective of the investigation was to establish the character of time distribution of flares and to study the flare mechanism in red dwarf stars. Observations were obtained with photographic method using photo-plates of Kodak and ORWO, on the wide-field (circular field with diameter of 4 ◦ 50 ′ ) Maksutov system 70/100/210 cm Meniscus-type telescope of the Abastumani observatory by means of multiple exposure method. Observational data containing information about flare stars and their flares obtained after processing photographic observations in 1969-1986 around Orion Trapezium has been published in the cumulative catalogue of flare stars in the Orion region (Natsvlishvili, 1991), where complete information about known (for that period) 490 flare stars and their 654 flares included. Out of these, 125 new flare stars and 182 flares of known flare stars were fixed in the Abastumani Astrophysical Observatory. Star AB461=TZ Ori turned out to be a short-period Cepheid (Natsvlishvili, 1994). After the publication of this catalogue new photographic material was obtained using the same methodology. On the basis of the new observations","PeriodicalId":35213,"journal":{"name":"Information Bulletin on Variable Stars","volume":"6187 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68620430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
