  1. 16. Dynamical Stability of Planetary Systems

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aikaterini Stergiopoulou; [2017]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 17. Development and simulation of an active target detector with GEM foil readout

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Elisabeth Rickert; [2017]
    Keywords : Physics and Astronomy;

    Abstract : At CERN, radioactive ion beams with energies of up to 10 MeV/u can be pro- duced by a newly commissioned post-accelerator, HIE-ISOLDE, which expands the possibilities for nuclear reaction studies. To investigate the collision properties of the ion beam with a target, an active gas–target detector is under development by the Reactions Group at the Nuclear Physics Division in Lund. READ MORE

  4. 18. Giant planet formation around HR8799

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

    Author : Dan Wallsby; [2017]
    Keywords : HR8799; Planet formation; Protoplanetary disks; Giant planets; Astronomy; Migration; Dynamics; Physics and Astronomy;

    Abstract : In the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. READ MORE

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

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Johan Appelgren; [2017]
    Keywords : Orbital stability; Dynamics; Exoplanets; Physics and Astronomy;

    Abstract : 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. READ MORE

  6. 20. Refining the orbits of the planets in HD 207832

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Emil Zadera; [2017]
    Keywords : stability; habitable zone; eccentricity; HD 207832; Physics and Astronomy;

    Abstract : The star, HD 207832, has two Jupiter-like planets on orbits with poorly constrained eccentricities. The eccentricities are 0.27 [sup]+0.22[/sup] [sub]-0. READ MORE
