1. 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

2. Hyper-velocity stars from globular clusters hosting intermediate-mass black holes
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : In 1988 Hills proposed that stars can gain velocities above 500 km s−1 if they are in a stellar binary which gets disrupted by a super massive black hole (SMBH). One of the stars would get trapped in an elliptical orbit around the SMBH while the other gets ejected and obtains a relatively high velocity. READ MORE

3. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. READ MORE

4. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge. However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. READ MORE

5. Modelling stellar streams around the Milky Way
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Stellar streams around the Milky Way (MW) have been observed by wide sky surveys, and studied to understand the mass distribution of the MW. This is because streams are formed by a disruption of a globular cluster or a dwarf galaxy under the influence of the gravitational field of the MW. READ MORE
