1. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure
University essay from Uppsala universitet/Observationell astrofysikAbstract : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. READ MORE

2. The Metallicity Structure of the Milky Way halo I : Creating a stellar catalogue of the distant halo’s red giants
University essay from Uppsala universitet/Observationell astrofysikAbstract : The Milky Way's halo is an approximately spherical distribution of stars surrounding the Galaxy that carries the history of the Milky Way. The outer halo is a Galactic region with long dynamical timescales largely built up by accreted material. 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. Leo II: a distant dwarf spheroidal galaxy
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : In this project aperture photometry has been performed for stars in the direction of the dwarf spheroidal galaxy Leo II. The observations were carried out using the Stro ̈mgren filters v, b and y, during three consecutive nights in 2003, out of which all but the first one turned out to be non-photometric. READ MORE
