  1. 1. Performance Evaluation of a 3D Printed Mirror Actuator : A Comparison with the James Webb Space Telescope

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Louise Leopoldsson; Ellen Lindsjö; [2023]
    Nyckelord :Actuator; James Webb Space Telescope;

    Sammanfattning : This study aims to investigate the similarities in precision and performance between a James WebbSpace Telescope mirror actuator, the part controlling the motion of the primary mirror segments,and two 3D printed replicas. The two replicas were made from the plastics PLA and PETGand based on the designs of Zachary Tong. LÄS MER

  3. 2. James Webb Space Telescope Observations of Jupiter’s Moon Europa

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Aulon Nura; Isac Engblom; [2023]
    Nyckelord :;

    Sammanfattning : The creation of life has puzzled humanity since the dawn of time. With the launch of thecutting-edge James Webb Space Telescope (JWST) at last year's closing, the next step in humanity'ssearch for life has been taken. LÄS MER

  4. 3. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Stephan Weissenböck; [2023]
    Nyckelord :Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

    Sammanfattning : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. LÄS MER

  5. 4. Using the James Webb Space Telescope to Find Carbon Dioxide on Ganymede

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Olof Helgesson; Oscar Lundin; [2023]
    Nyckelord :;

    Sammanfattning : The aim of this bachelor's thesis is to search for CO₂ on Ganymede by studyingobservations taken by the James Webb Space Telescope and in doing so, create aprocessing pipeline for JWST data. The data is collected by JWST's Near InfraredSpectrograph instrument which is used for spectroscopy in the near infrared spectrum. LÄS MER

  7. 5. Estimating stellar limb darkening using exoplanet transits

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

    Författare :Sora Ishida; [2023]
    Nyckelord :Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

    Sammanfattning : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. LÄS MER
