  1. 1. Abundances of iron-peak elements in disk and bulge giant stars from high-resolution optical spectra

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

    Författare :Maria Lomaeva; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Context. The formation and evolution of the Galactic bulge and the Milky Way is still a debated subject. Observations of, e.g. LÄS MER

  2. 2. Potassium in the Galactic thin and thick discs

    Kandidat-uppsats, Lunds universitet/Astronomi

    Författare :Carina Norregaard; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : To understand the evolution of our galaxy, the chemical abundance patterns and trends within the stars of the different regions are explored. The process of synthesizing these elements reveals key details about the way the stars and, therefore, the galaxy formed. LÄS MER

  3. 3. Mapping the present-day chemical abundance structure of the Solar neighbourhood: O & Si

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

    Författare :Kristiina Verro; [2017]
    Nyckelord :astrophysics; stellar spectroscopy; abundance analysis; solar neighbourhood; massive stars; Galaxy; Physics and Astronomy;

    Sammanfattning : Context. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. LÄS MER

  4. 4. Radial migration of stars, measured in N-body simulations

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

    Författare :Daniel Mikkola; [2017]
    Nyckelord :N-body; simulations; galaxies; radial migration; stars; Physics and Astronomy;

    Sammanfattning : The purpose of Galactic archaeology is determining the history of the Milky Way (MW) Galaxy. To do this one uses observational data from stellar populations in terms of properties such as kinematics, chemistry, ages, and evolution. LÄS MER

  5. 5. It Takes Water and Energy in a Block

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Alvin Hilmersson; Fanny Norén; Alexander Ullén; Lucas Wiik; [2016]
    Nyckelord :Energy Water Greywater Reuse Save Residental;

    Sammanfattning : This report investigates sustainable solutions for electricity and water savings in an urban neighbourhood consisting of a block of buildings in Sege Park, Malmö. The solutions were evaluated in terms of sharing, producing, recycling and saving. LÄS MER
