  1. 1. 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

  3. 2. 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

  4. 3. 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

  5. 4. 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

  7. 5. Spectroscopic analysis of exoplanet atmospheres : Ground-based high-resolution atmospheric characterization of hot Jupiters using near infrared spectroscopy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Emelie Stoltz Årevik; [2015]
    Nyckelord :ground-based high-resolution atmospheric atmosphere characterization hot Jupiters near infrared spectroscopy;

    Sammanfattning : This report is exploring the possibility of characterizing hot Jupiter atmospheres using ground-based high-resolution spectroscopy. The ESO CRIRES infrared spectrometer is selected as the observing tool. Simulated observations are computed for known transiting systems. LÄS MER
