Observational study of F spectral type high proper motion stars

In this study, chemical abundance analysis of high resolution echelle spectra obtained in 3900 – 6800 Å region for F-type high proper motion dwarf stars, namely, HD 102870, BD +20 3603, BD +25 1981, BD +42 3607, HD 3567, HD 6755, HD 84937 from the ELODIE stellar library, has been performed. Under the framework of the thesis, in a sample of 54 stars in total in the library, mostly metal-poor 7 program stars with relatively high proper motions are chosen for the analysis. In order to reveal their physical nature and to put forth any possible relationship between their computed Galactic space velocities and chemical compositions, kinematics computations have been performed and their Galactic orbital parameters have been obtained in order for their Galactic population membership status to be determined.
