1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

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. Development and testing of algorithms for optimal thruster command distribution during MTG orbital manoeuvres
University essay from Luleå tekniska universitet/RymdteknikAbstract : An accurate satellite attitude and orbit control is a key factor for a successful mission. It guarantees for example sun acquisition on solar panels, fine pointing for optimal telescope usage or satellite lifting to reach higher orbits, when required. READ MORE

5. From the bulge region to the outer disk: Tracing the α-enhancement level in the Galactic thin and thick disks
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : One of the biggest mysteries astronomers wish to unveil is the formation and evolution of galaxies. Properties of our own galaxy, the Milky Way, can provide great insight into these. The star formation rate (SFR) and whether it varies with distance from the galactic centre (GC), is one of these properties. READ MORE
