6. Detailed chemical abundances of neutron-capture elements - from 523 local giant stars
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Purpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. READ MORE

7. The astronomical consequences of primordial black holes
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : In the radiation or early matter dominated eras of the Universe, there is a theoretical possibility for the formation of black holes (BHs). These primordial black holes (PBHs) have been thought of as a possible candidate for dark matter (DM), and an attractive one at that as it would explain DM using only baryonic physics. READ MORE

8. Abundances of iron-peak elements in disk and bulge giant stars from high-resolution optical spectra
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : Context. The formation and evolution of the Galactic bulge and the Milky Way is still a debated subject. Observations of, e.g. READ MORE

9. A study of the stellar populations in the Kepler field
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Studying the formation and evolution of galaxies is a fundamental problem in astronomy that warrants repeated investigation by astronomers. How do spiral galaxies like our own come to have its distinct spiral arms? How do stars and their properties change over time and will they continue to evolve in the same manner? To try and attempt to answer such questions we need to look to our own Galaxy the Milky Way. READ MORE

10. The Galactic thick disk: a stellar population in its own right?
University essay from Uppsala universitet/Observationell astrofysikAbstract : The Galactic disk is home of many billion stars, one of which isour Sun. The stellar population of which the Sun is a member residesin the vertically thin spiral structure of the disk. There is a seconddisk population, the so-called thick disk, that has somewhat dierentspatial, kinematic and chemical properties as compared to the thindisk. READ MORE
