1. 1. Planes of satellite galaxies

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Jessica Laura Erika Kocher; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. LÄS MER

3. 2. A Close Look at the Transient Sky in a Neighbouring Galaxy

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Kiran Tikare; [2020]
   Nyckelord :Astrophysical Transients; Optical Transients; Microlensing; Variable Stars; Andromeda Galaxy; Forced Aperture Photometry; Time Domain Astronomy; Sky Survey; Zwicky Transient Facility; Machine Learning; Big Data Science;

   Sammanfattning : Study of the time variable sources and phenomena in Astrophysics provides us with important insights into the stellar evolution, galactic evolution, stellar population studies and cosmological studies such as number density of dark massive objects. Study of these sources and phenomena forms the basis of Time Domain surveys, where the telescopes while scanning the sky regularly for a period of time provides us with positional and temporal data of various Astrophysical sources and phenomena happening in the Universe.

4. 3. Stars Eating Planets

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :John Wimarsson; [2020]
   Nyckelord :Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

   Sammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER

5. 4. Can tidal interactions produce MGC1?

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Författare :Eric Andersson; [2018]
   Nyckelord :globular cluster; MGC1; Andromeda; M31; galaxy; dwarf galaxy; tidal interactions; Physics and Astronomy;

   Sammanfattning : The globular cluster population of large spiral galaxies can be divided into two populations: one population which formed in-situ and one which has been assembled through capture of clusters that have been tidally stripped away from other galaxies during close encounters or mergers. In this work, I focus on the globular cluster MGC1, which is orbiting the M31 galaxy. LÄS MER

7. 5. Inquiries into the absence of extended globular clusters in the Milky Way galaxy

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Kristina Doxsee; [2010]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Thirteen stellar objects known as extended globular clusters were found in the Halo of the Andromeda Galaxy. Three of these extended clusters have quantitative properties which are subsequently used to determine whether clusters of extended size could survive in the orbits of the Milky Way Galaxy. LÄS MER
