  1. 1. Chaos in Stellar Dynamics - Outcomes of Binary-Single interactions in Globular Clusters

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

    Författare :Lucas Hellström; [2020]
    Nyckelord :Stellar Dynamics; Binary-Single interactions; Dynamical encounters; Additional processes; Physics and Astronomy;

    Sammanfattning : Gravitational encounters between a single star and a binary system can frequently occur in the cores of dense stellar systems like globular clusters. These three-body scattering encounters can lead to a variety of outcomes since the energy of the binary components can be exchanged with the interacting single star. LÄS MER

  3. 2. Multi-planetary Systems from Simulated TESS Transit Timing Variations

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Lucas Hellström; [2018]
    Nyckelord :Transit timing variations; TTV; TESS; Physics and Astronomy;

    Sammanfattning : A transit is a phenomenon where a planet passes between its host star and an observer blocking out part of the light from the star. This decrease can be measured and used to gain information about the planet. The Kepler and TESS telescopes are examples of space telescopes using the transit method to detect exoplanets. LÄS MER
