  1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

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

    Författare :Elias Önerud; [2023]
    Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

  2. 2. Quality Assessment of the Fabry-Pérot Wavelength Calibration for CRIRES+ : Student Project Report

    L3-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Christopher Borchert; [2023]
    Nyckelord :;

    Sammanfattning : The data reduction software of CRIRES+, a new high-resolution spectrometer installed at VLT, features a calibration routine that uses data from a Fabry-Pérot étalon. The quality of this calibration mode is assessed in this project report. LÄS MER

  3. 3. Planning Observations of Terrestrial ExoplanetsAround M Type Stars with CRIRES+

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Jonas Zbinden; [2021]
    Nyckelord :;

    Sammanfattning : In recent decades, thousands of exoplanets have been discovered. The next step is to characterize theobserved planets in terms of their radii, masses, density, physical conditions and composition of theiratmospheres. LÄS MER

  4. 4. Implementing an Algorithm for Spectrum Extraction of Circumstellar Objects with High-Dispersion Spectroscopy

    Master-uppsats, Stockholms universitet/Institutionen för astronomi

    Författare :Marcus Karlsson; [2019]
    Nyckelord :Astronomy; Spectroscopy; Exoplanets; Circumstellar Objects; Direct Imaging;

    Sammanfattning : In this thesis project, we study the field of high-dispersion spectroscopy and methods for extracting the spectrum of circumstellar objects such as exoplanets from the combined signal of a stellar system. One of the only techniques for detecting absorption lines in exoplanetary atmospheres is to directly image a planet and record the reflected light. LÄS MER

  5. 5. Identification of elements and molecules in the spectra of an M dwarf star using high resolution infrared spectroscopy.

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

    Författare :Markus Pudas; [2017]
    Nyckelord :M dwarf stars; line list ; spectroscopy ; high resolution infrared; telluric spectra;

    Sammanfattning : M dwarfs are abundant and long-lived stellar objects. The formation of planets around stars in stellar systems is believed to be metallicity dependent. To determine the metallicity with synthetic spectrum analysis, the elements producing the absorption lines ofthe spectra first have to be identified. LÄS MER
