Zinc abundances of stars in the Milky Way
Modeller som beskriver a¨mnesyntesen i stja¨rnor och supernovor har haft begra¨nsad framg˚ang med att f¨orklara de observerade halterna i stja¨rnor. Dessa modeller a¨r inkonsekventa f¨or olika grund¨amnen och det saknas en komplett bild o¨ver den a¨mnesberikningen som sker i v˚art universum. Syntes av ¨amnen i stj¨arnor beror p˚a m˚anga faktorer som ursprunglig kemiska sam- mansa¨ttning hos stja¨rIn this work we study the spectra of 423 stars in the Milky Way disk in order to determine their zinc abundances. The methodology to determine elemental abundances consists of synthesising sets of spectra with varying zinc abundances and comparing them with the observed spectra to find the best fit. The aim of the project was to compare the spectra syn- thesis method used here to Bensby et al. (2014
