  1. 1. The Effect of Gravitational Encounters on Binary Planetesimals

    University essay from Lunds universitet/Astronomi

    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

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

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

    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

  3. 3. Stars Eating Planets

    University essay from Lunds universitet/Astronomi

    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

  4. 4. Mean Motion Resonances and Planetary Scattering

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

    Author : Erik Dahlöf; [2018]
    Keywords : mean motion resonance; orbit resonance; planetary dynamics; planet-planet scattering; planetary scattering; eccentricity; inclination; planet systems; disturbing force; orbit dynamics; orbital elements; planets; exoplanets; scattering phase; relaxation; dynamical instabilities; N-body; protoplanetary disk; planet migration; eccentricity damping; inclination damping; planet-disk interactions; Physics and Astronomy;

    Abstract : The observed distribution of giant exoplanet eccentricities and inclinations are significantly larger than what is measured for their Solar system analogues, Jupiter and Saturn. Since the first observations of exoplanets, planet-planet scattering has been proposed as a possible mechanism for exciting the eccentricities and inclinations of giant exoplanets. READ MORE

  5. 5. The Dynamical Evolution of Young Clusters. With a focus on the effects on planetary systems

    University essay from Lunds universitet/Astronomi

    Author : Clément Bonnerot; [2011]
    Keywords : Physics and Astronomy;

    Abstract : Stars form in clusters or groups. In these crowded environments, they are likely to experience encounters with one another. These encounters may perturb their planetary systems and cause the ejection of one or more planets. READ MORE
