2. Something 3D
University essay from Uppsala universitet/Observationell astrofysikAbstract : Modelling stellar structures and comparing them with observationsis a very important step when it comes to verifying our theories aboutstellar evolution. Three-dimensional reconstruction is therefore impor-tant and in the case of certain stellar types it makes for a large portionof the ongoing research. READ MORE

3. 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

4. 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

5. 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.
