  1. 1. Matter-streams as sources of the Kerr metric

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Julian Boy; [2022]
    Nyckelord :General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Sammanfattning : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. LÄS MER

  3. 2. Forbidden oxygen in the Milky Way disk

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Asma Sahli; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Oxygen is produced inside massive stars and dispersed into the interstellar medium mainly through type II supernovae explosions. This element, which is the third most abundant one in the Universe, plays an important role in tracing the Galactic chemical history and evolution. LÄS MER

  4. 3. Chemical composition of giant planet hosts

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Frida Ekstrand; [2017]
    Nyckelord :chemical composition; planet hosts; stellar twins; differential abundance analysis; Physics and Astronomy;

    Sammanfattning : Does the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found.

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

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

    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

  7. 5. Sportcenter i Västertorp

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Andreas Gårdendal; [2014]
    Nyckelord :Architecture; Urban planning; Stockholm; Västertorp; Mellanbergsparken; Hägerstensåsen; Bath-house; Bathhouse; Swimming-bath; Swimming pool complex; Sports center; Fitness center; Gym; Group training; Cubicle; Locker room; Sports hall; Arkitektur; Stadsplanering; Stockholm; Västertorp; Mellanbergsparken; Hägerstensåsen; Badhus; Sportcenter; Gym; Gruppträning; Omklädningsrum; Idrottshall;

    Sammanfattning : Stockholm Stad behöver utöka kapaciteten på sina badhus samt idrottsanläggningar. Därtill är renoveringsbehovet stort på samtliga badhus. Badet i Västertorp täcker ett stort område och är populärt men behöver nu rivas pga. det dåliga skicket. LÄS MER
