1. 6. The retention of black holes in globular clusters

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

   Författare :Wuxueman Liu; [2021]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. LÄS MER

3. 7. The fate of stars born in gas-rich high redshift galaxies

   Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Floor van Donkelaar; [2021]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : One of the greatest challenges astronomers are facing today is understanding how galaxies form. We know that the Milky Way is a spiral disk galaxy, similar to many others we see in the sky, therefore the Milky Way is a benchmark for understanding the inner workings of disk galaxies. LÄS MER

4. 8. A forecasting approach to estimating cartel damages : The importance of considering estimation uncertainty

   Magister-uppsats, Södertörns högskola/Nationalekonomi

   Författare :Didrik Prohorenko; [2020]
   Nyckelord :Forecasting approach; estimation uncertainty; merger simulation; cartels; t-test; small sample size; damages; counterfactual analysis;

   Sammanfattning : In this study, I consider the performance of simple forecast models frequently applied in counterfactual analysis when the information at hand is limited. Furthermore, I discuss the robustness of the standard t-test commonly used to statistically detect cartels. LÄS MER

5. 9. 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

7. 10. 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
