1. Measuring copper abundances in the Galactic Bulge
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

2. Origin of blue straggler stars in the Milky Way halo
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. READ MORE

3. Post-Main Sequence Habitability for Outer Solar System Moons
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : The search for extra-terrestrial life is guided by the classification of promising candidate worlds. In this classification the habitable zone acts as a measure for the perceived habitability of a circumstellar body. Habitable zone definitions vary between using a conservative and an optimistic limit. READ MORE

4. Measuring the Characteristic Sizes of Convection Structures in AGB Stars with Fourier Decomposition Analyses : the Stellar Intensity Analyzer (SIA) Pipeline.
University essay from Uppsala universitet/Teoretisk astrofysikAbstract : Context. Theoretical studies predict that the length scale of convection in stellar atmospheres isproportional to the pressure scale height, which implies that giant and supergiant stars should have convection granules of sizes comparable to their radii.

5. Dynamical Stability of Planetary Systems
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : The study of dynamical stability in planetary systems has become possible during the last few decades due to the development of numerical methods for long-term integrations of N-body systems. Since the 90’s the number of exoplanet detections has been increased significantly, making the simulations of other real planetary systems besides the Solar System feasible. READ MORE
