  2. 1. Photometry of Resolved Stellar Populations in Local Group Galaxies

    Author : Daniel Faria; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; Astronomy; Local Group; Galaxy: halo; Galaxies: dwarf; Galaxy: stellar content; Galaxies: photometry; Techniques: photometric; Stars: fundamental parameters;

    Abstract : This thesis presents results from two projects using photometric observations to investigate stellar populations in Local Group galaxies. In the first project, Strömgren photometry is used to study stellar populations in dwarf spheroidal galaxies. READ MORE

  4. 2. Star clusters as engines of galaxy evolution

    Author : Mattia Sirressi; Angela Adamo; Matthew J. Hayes; Johan Fynbo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Stars form and live in hierarchical structures such as star clusters on the smallest scales up to groups of galaxies on the largest scales. The role of young and massive star clusters in the evolution of the host galaxies is one of the most active fields of research in modern astronomy. READ MORE

  5. 3. Dark Matter in the Solar System, Galaxy, and Beyond

    Author : Axel Widmark; Jens Jasche; Malcolm Fairbairn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter: phenomenology; dark matter: indirect detection; dark matter: particle nature; Galactic dynamics; Galactic composition; Theoretical Physics; teoretisk fysik;

    Abstract : There is evidence that dark matter constitutes a majority of the Universe's matter content. Yet, we are ignorant about its nature. Understanding dark matter requires new physics, possibly in the form of a new species of fundamental particles. READ MORE

  6. 4. Galactic Structure Revealed by Space Astrometry

    Author : Johan Holmberg; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; Galactic structure; Milky Way Galaxy; Galactic kinematics and dynamics; Galactic chemical evolution; moving groups; solar neighbourhood; dark matter; astrometry; Hipparcos; space research; Astronomy; rymdvetenskap; kosmisk kemi; Space technology; Rymdteknik; Fysicumarkivet A:2001:Holmberg;

    Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.

  7. 5. Interacting Giants and Compact Stars

    Author : Alexey Bobrick; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stars Binaries: General; stars : neutron; stars : subdwarfs; stars : supergiants; hydrodynamics; nuclear reactions; nucleosynthesis; abundances; stars Binaries: General; stars : neutron; stars : subdwarfs; stars : supergiants; hydrodynamics; nuclear reactions; nucleosynthesis; abundances; Fysicumarkivet A:2021:Bobrick;

    Abstract : This thesis is based on four papers dealing with various aspects of interactions in binary stars. Interactions between stars occur at nearly all stages of their evolution and can take many forms. READ MORE
