  1. 1. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lucian Spitzner; [2023]
    Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER

  3. 2. Search for transiting exoplanets in globular clusters

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Oskar Nilsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. LÄS MER

  4. 3. Detecting Transiting Exoplanets in Crowded Fields

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Eddie Larsson; [2022]
    Nyckelord :Transit method; Globular cluster; crowded environments; exoplanets; transiting exoplanets; Physics and Astronomy;

    Sammanfattning : The first planet orbiting a main-sequence star was discovered in 1995. Since then more than 4000 additional exoplanets have been discovered. This is a rapidly evolving field in astrophysics. One of the most common ways to detect an exoplanet is through transit, as the brightness of the host star decreases. LÄS MER

  5. 4. Spectroscopic model characterisation of hot exoplanet atmospheres

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

    Författare :Elin Sandvik; [2022]
    Nyckelord :Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Sammanfattning : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. LÄS MER

  7. 5. Searching for Exoplanets in K2 Data

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Iskra Georgieva; [2018]
    Nyckelord :exoplanets; transit method;

    Sammanfattning : The field of extrasolar planets is undoubtedly one of the most exciting and fast-moving in astronomy. Thanks to the Kepler Space Telescope, which has given us the Kepler and K2 missions, we now have thousands of planets to study and thousands more candidates waiting to be confirmed. LÄS MER
