  1. 11. A study of power spectral densities of real and simulated Kepler light curves

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Holger Weishaupt; [2015]
    Nyckelord :Exoplanet detection; transit method; stellar variability; light curve simulation; power spectrum; power spectral density estimate;

    Sammanfattning : During the last decade, the transit method has evolved to one of the most promising techniques in the search for extrasolar planets and the quest to find other earth-like worlds. In theory, the transit method is straight forward being based on the detection of an apparent dimming of the host star’s light due to an orbiting planet traversing in front of the observer. LÄS MER

  3. 12. Combining astrometric and radial velocity data for exoplanet detection

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

    Författare :Viktor Holmelin; [2013]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Context: The Gaia satellite will be provide astrometry with micro-arcsecond accuracy. This will allow for the determination of the orbital elements of exoplanets with measurable astrometric signature. LÄS MER

  4. 13. Unearthing exoplanets

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

    Författare :Joel Wallenius; [2012]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This is a bachelor thesis bent on introducing the field of exoplanet research. It primarily includes descriptions of the various detection methods, with some detail into how the methods yield parameter estimates by means of least-squares algorithms. LÄS MER

  5. 14. Spectroscopic characterization of transiting exoplanets : A study of the possibility to detect atmospheres around exoplanets using SIMPLE

    Kandidat-uppsats, Observationell astrofysik

    Författare :Pierre Waldén; Erik Aronson; [2011]
    Nyckelord :exoplanet; atmosphere; spectrum; extra solar planet; spectroscopy; SIMPLE; E-ELT; ESO; spectrometer; telescope; spectral features; noise; signal to noise; S N; planet; star; red dwarf; atmospheric features; Super-Earth; Earth-like;

    Sammanfattning : This report describes simulations of observations with the near-infrared high-resolution spectrometer SIMPLE that is proposed to the ESO telescope E-ELT. We simulate M4 and G2 stars with transiting Earth-like planets and the goal is to distinguish spectral features originating from the atmosphere of the exoplanet. LÄS MER
