  1. 1. Have Radial Velocity Surveys Missed Any Planets?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Shah Raj; [2021]
    Nyckelord :radial velocity survey; transit method; exoplanet; habitable zone; habitable zone boundaries; HZ; early Mars; recent Venus; stability; instability; chaos; REBOUND; MEGNO; MEGNO maps; Hill sphere; stable systems; unstable systems; Physics and Astronomy;

    Sammanfattning : The project was aimed at numerically assessing exoplanetary systems to distinguish their capabilities of hosting additional planets. The shortcomings of the radial velocity method sometimes causes hindrance in the detection of terrestrial planets. LÄS MER

  3. 2. The Solar System Around a Binary Star

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Jesper Nielsen; [2019]
    Nyckelord :planetary system stability; binary star; Physics and Astronomy;

    Sammanfattning : The observations of circumbinary planets have confirmed that these can in fact be stable. While previous studies on circumbinary planets have been done, not many have been made on systems containing multiple circumbinary planets on eccentric orbits. LÄS MER

  4. 3. Dynamical Stability of Planetary Systems

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Aikaterini Stergiopoulou; [2017]
    Nyckelord :;

    Sammanfattning : The study of dynamical stability in planetary systems has become possible during the last few decades due to the development of numerical methods for long-term integrations of N-body systems. Since the 90’s the number of exoplanet detections has been increased significantly, making the simulations of other real planetary systems besides the Solar System feasible. LÄS MER

  5. 4. Can there be an Earth-like planet in HD37605?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Johan Appelgren; [2017]
    Nyckelord :Orbital stability; Dynamics; Exoplanets; Physics and Astronomy;

    Sammanfattning : Detection of Earth-mass planets on orbits around 1 AU with the radial velocity method has so far not been possible, the Doppler velocity they induce on their host star is too small to be detected. Planetary systems detected with the radial velocity method might then contain undetected Earth-like planets. LÄS MER
