1. 1. Black Hole Dynamics in Stellar Clusters

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Markus Strickert; [2022]
   Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

3. 2. Escaping Compact Object Binaries from Globular Clusters

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Annie Csomor; [2022]
   Keywords : Compact object binaries; binary black holes; BH-NS binaries; escaping binaries; globular clusters; escaping compact object binaries from globular clusters; escaping compact binaries; Physics and Astronomy;

   Abstract : Since 2015, the LIGO-Virgo-KAGRA scientific collaboration (LVK) has detected gravitational waves from more than 90 merging compact object binaries using ground-based interferometric detectors. Compact objects orbiting in binary systems emit gravitational waves leading to a loss of energy. READ MORE

4. 3. The Effect of Gravitational Encounters on Binary Planetesimals

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : John Gillan; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Binary planetesimals in the Kuiper belt can experience close encounters with other bodies. These encounters can disturb the orbital dynamics of the binary in several ways. Energy can be added to the system by the impactor body and lead to the disruption of the binary. READ MORE

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

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

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

   Abstract : 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. READ MORE

6. 5. Stars Eating Planets

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : John Wimarsson; [2020]
   Keywords : Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

   Abstract : 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. READ MORE
