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. Testing the multi-epoch luminosity function of asymptotic giant branch stars in the Small Magellanic Cloud with VISTA
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : The physics pertaining to the asymptotic giant branch (AGB) phase of stellar evolution has been studied for many years. However, the mechanics behind many characteristics displayed at this stage are still not fully understood. READ MORE

3. Photometry of carbon star wind-modelsat solar & sub-solar metallicities
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Asymptotic giant branch stars (AGB) are cool, luminous stars withan initial mass of approximately 0.8 to 8 solar masses. Towards theend of their lives they undergo heavy mass loss, a process thoughtto be caused by dust-driven winds. When it comes to carbon-richAGB stars, i. 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. Pulsation Properties in Asymptotic Giant Branch Stars
University essay from Uppsala universitet/Teoretisk astrofysikAbstract : Asymptotic Giant Branch (AGB) stars are stars with low- to intermediate mass in a late stage in their stellar evolution. An important feature of stellar evolution is the ongoing nucleosynthesis, the creation of heavier elements. READ MORE
