  1. 6. Detecting Earth-like exoplanets using high-dispersion nulling interferometry

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Germain Garreau; [2021]
    Nyckelord :Applied Physics; Instrumental Optics; Exoplanets Detection; Interferometry; Spectroscopy; Tillämpad fysik; Instrumentoptik; Exoplaneter upptäckt; Interferometri; Spektroskopi;

    Sammanfattning : The detection of Earth-like exoplanets and the characterization of their atmospheres is a challenge one needs to solve to assess their habitability and the presence of life in the universe. If this challenge is still unresolved today, even in the era of giant telescopes, it is mainly because of the very high contrast between these exoplanets and their host star and also their proximity.

  3. 7. High resolution imaging observations of exoplanet host stars

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Kaltrina Kajtazi; [2020]
    Nyckelord :Speckle imaging; Speckle interferometry; High resolution imaging; Short integration time; Binaries; Exoplant hosts; Stellar properties; WIYN; Gemini; Orbital period; Physical separation; Angular separation; magnitude difference; Physics and Astronomy;

    Sammanfattning : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. LÄS MER

  4. 8. Detailed analysis of the chemical composition of stars harboring Earth-like planets

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Lorena Acuña Aguirre; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. LÄS MER

  5. 9. Implementing a pipeline to search for transiting exoplanets : application to the K2 survey data

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

    Författare :Hrafn N. H. Weishaupt; [2018]
    Nyckelord :Exoplanet detection; Transiting exoplanet; Transit method; Kepler; K2;

    Sammanfattning : The detection of exoplanets has rapidly evolved to one of the most important frontiers of astronomical and astrophysical research. The recent decades have seen the development of various techniques for detecting exoplanets. LÄS MER

  7. 10. Solar System analogues among exoplanetary systems

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

    Författare :Maria Lomaeva; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past two decades many discoveries of exoplanets have been made, which have drawn much attention to extrasolar planetary systems. In this work we study the composition of these systems and search for analogues of the Solar System. We considered the planets in the database at exoplanet.eu. LÄS MER
