  1. 1. 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

  3. 2. 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

  4. 3. Exploring the Diversity of Exoplanets

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Rebecka Svensson; [2021]
    Nyckelord :Exoplanets; Super-Earth; Sub-Neptune;

    Sammanfattning : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. LÄS MER

  5. 4. The chemical composition of hot and cold gas giants

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

    Författare :Linn Eriksson; [2016]
    Nyckelord :Planet formation; hot Jupiter; pebble accretion; Physics and Astronomy;

    Sammanfattning : Exoplanet surveys have identified a category of giant planets that orbit very close to their host stars - the so-called hot Jupiters. The origin of such hot Jupiters is a long standing puzzle and has been closely investigated since the first discovery of such planets in 1995. LÄS MER

  7. 5. The thermal structure of exoplanet atmospheres

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

    Författare :Matthew Agnew; [2015]
    Nyckelord :exoplanet; atmospheres; cold trap; hot jupiter; thermal inversion; thermal structure; Physics and Astronomy;

    Sammanfattning : Context. The discovery of hot Jupiters, giant gas exoplanets on tight orbits close to their host star, has proven instrumental in the study of exoplanet atmospheres through transit spectroscopy. LÄS MER
