Chaotic orbits with initial conditions outside corotation support the spiral structure of the galaxy due to the phenomenon of stickiness close and along the unstable asymptotic manifolds of the unstable periodic orbits. These orbits are diffused outwards after about 13 rotations of the bar. During this time, the spiral structure is clearly visible and then it fades out gradually. The diffusion time for the majority of the chaotic orbits with initial conditions inside corotation is much longer than the age of the Universe. These orbits support mainly the outer parts of the bar. However, a part of the chaotic orbits inside corotation are diffused outwards fast and support the spiral structure. <\/jats:p>","DOI":"10.1142\/s0218127411029732","type":"journal-article","created":{"date-parts":[[2011,7,8]],"date-time":"2011-07-08T10:14:41Z","timestamp":1310120081000},"page":"2221-2233","source":"Crossref","is-referenced-by-count":5,"title":["DIFFUSION OF CHAOTIC ORBITS IN BARRED SPIRAL GALAXIES"],"prefix":"10.1142","volume":"21","author":[{"given":"M.","family":"HARSOULA","sequence":"first","affiliation":[{"name":"Research Center for Astronomy, Academy of Athens, Soranou Efesiou 4, GR-11527, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"KALAPOTHARAKOS","sequence":"additional","affiliation":[{"name":"Research Center for Astronomy, Academy of Athens, Soranou Efesiou 4, GR-11527, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"CONTOPOULOS","sequence":"additional","affiliation":[{"name":"Research Center for Astronomy, Academy of Athens, Soranou Efesiou 4, GR-11527, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2009.15583.x"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2008.14273.x"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127408022172"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1007\/s10569-010-9282-6"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2009.14427.x"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2010.17748.x"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361:20054653"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1051\/0004-6361:20077504"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2008.13331.x"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2006.11021.x"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2966.2006.10914.x"}],"container-title":["International Journal of Bifurcation and Chaos"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218127411029732","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T19:56:16Z","timestamp":1565121376000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218127411029732"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,8]]},"references-count":11,"journal-issue":{"issue":"08","published-online":{"date-parts":[[2011,11,20]]},"published-print":{"date-parts":[[2011,8]]}},"alternative-id":["10.1142\/S0218127411029732"],"URL":"https:\/\/doi.org\/10.1142\/s0218127411029732","relation":{},"ISSN":["0218-1274","1793-6551"],"issn-type":[{"value":"0218-1274","type":"print"},{"value":"1793-6551","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,8]]}}}
