  1. 1. 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

  3. 2. Predicting bat occurrence : evaluation of a connectivity-based habitat index for Swedish bats

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Gesa von Hirschheydt; [2018]
    Nyckelord :bats Chiroptera ; bat habitat index; ecological impact assessment; flight friction; cost distance analysis; landscape permeability;

    Sammanfattning : Ecological impact assessments are required for all large infrastructure or exploitation projects because of their effects on environment and species. Methods that would make such assessments more standardised, efficient and reliable are highly desirable in today’s society, where many species are decreasing due to human-induced habitat modifications.

  4. 3. Nucleosynthesis in accretion disks around black holes

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

    Författare :Neige Frankel; [2017]
    Nyckelord :accretion disk; Nucleosynthesis; black hole; high energy; white dwarf tidal disruption; Physics and Astronomy;

    Sammanfattning : Nucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. LÄS MER

  5. 4. Identification of elements and molecules in the spectra of an M dwarf star using high resolution infrared spectroscopy.

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Markus Pudas; [2017]
    Nyckelord :M dwarf stars; line list ; spectroscopy ; high resolution infrared; telluric spectra;

    Sammanfattning : M dwarfs are abundant and long-lived stellar objects. The formation of planets around stars in stellar systems is believed to be metallicity dependent. To determine the metallicity with synthetic spectrum analysis, the elements producing the absorption lines ofthe spectra first have to be identified. LÄS MER
