It states that the chemical composition of the photospheres of two (or more) stars born from the same interstellar medium will remain the same for most of their lifetime. When chemically non-homogeneous binary stars are observed, this assumption is challenged. In this paper, some possible explanations for such binaries are discussed, and some example studies are presented</dc:description><dc:description xml:lang="sl">Predpostavka kemične homogenosti je ključna predpostavka v mnogih astrofizikalnih raziskavah, predvsem na področju Galaktične arheologije. Na njeni podlagi predvidevamo, da kemična struktura fotosfer dveh (ali več) zvezd, ki so nastale iz enake medzvezdne snovi, ostane enaka večino njihovega življenja. Ko pri opazovanjih naletimo na dvojne zvezde, ki so kemijsko nehomogene, se poraja dvom o pravilnosti te predpostavke. V tem članku je opisanih nekaj mehanizmov, ki bi takšne dvojne zvezde razložili, predstavljenih pa je tudi nekaj raziskav, ki so se ukvarjale s to problematiko</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-HA5HNXRB"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-HA5HNXRB" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-HA5HNXRB/f-3ee-4661ff2491-4a1613-814011a8bd6b/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-HA5HNXRB/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-HA5HNXRB" /></ore:Aggregation></rdf:RDF>
