Abstract
Nedavna otkrića varijabilnosti inteziteta međuzvjezdanih spektralnih linija ukazuju na moguće postojanje brzih i vrlo malih struktura materije u međuzvjezdanom mediju, reda veličine od 10 do 100 astronomskih jedinica (AU). U ovom radu pažnja je bila posvećena zvijezdama aktivnog zvjezdorodnog područja η Carinae, u kojem je vjerojatnija prisutnost spomenutih struktura, zbog gustoće okolnog plina i prašine. Spomenuto potvrđuju i rezultati rada, gdje sam uočila varijabilnost međuzvjezdanih... More apsorpcijskih linija na većem broju spektara, nego što je to ranije bilo primijećeno. U rezultatima su analizirane vrijednosti radijalnih brzina varirajućih komponenti, vremenske epohe unutar kojih su vrijednosti uočene, te njihova manifestacija na profil pojedine linije. Less
Abstract (english)
Recent discoveries of variability in interstellar spectral line intensity indicate possible resence of fast and very small structures of matter in interstellar media, ranging from 10 to 100 astronomical units (AU). In this paper, attention was given to the stars of active stellar region η Carinae, where the presence of the mentioned structures is more likely due to the density of surrounding gas and dust. This is also confirmed by the results of this thesis, where I have found... More variability of interstellar absorption lines in a bigger sample of spectra, than it has been previously observed. Radial velocities of the variable components, the time periods within which the variability was observed and its manifestation on the profile of a particular line have been analysed in the results.
