   Sammanfattning : In this report we present the testing and development made using the Lund Observatory Vacuum Echelle Spectrograph (LOVES) during the last few years. Hardware development includes an assembly from base components due to relocation and necessary calibrations of the optics. LÄS MER

3. 2. Identifying Moving Groups Using Elemental Abundances - A Study of KFR08

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Petter Thorén; [2011]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : In this work we study nine Hipparcos stars that has been identified as members of the KFR08 stellar stream by Bobylev et al. (2010). We perform high-resolution elemental abundance analysis on these stars using spectra from several sources (ELODIE, HIRES, MIKE and UVES) and the abundance analysis method from Bensby et al. (2003).
