  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. 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

  4. 3. Can planet formation explain the observed differences in the chemical composition of binary stars?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Rebecca Forsberg; [2017]
    Nyckelord :binary stars; planet formation; protoplanetary disc; Physics and Astronomy;

    Sammanfattning : A suggested explanation for the observed differences in chemical abundances in binary stars has been planet formation (e.g. Tucci Maia et al. 2014). LÄS MER

  5. 4. 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
