  1. 1. ’’en starkt lysande stjärna’’

    Kandidat-uppsats, Göteborgs universitet/Institutionen för pedagogik, kommunikation och lärande; Göteborgs universitet/Institutionen för pedagogik, kommunikation och lärande

    Författare :Carolina Olsson; Evelina Kind; Malin Lange; [2024-02-26]
    Nyckelord :Barn i behov av särskilt stöd; gråzonsbarn; förskollärares upplevelse; specialpedagogers upplevelse; särskilt stöd;

    Sammanfattning : I förskolans läroplan skrivs ambitiösa mål fram om hur verksamheten ska utformas efter alla barn som medverkar i den. Den lyfter också att om ett barn behöver särskilt stöd ska de få det, vare sig det är tillfälligt eller varaktigt. LÄS MER

  3. 2. Exocomets in the β Pictoris system

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

    Författare :Klaudia Jaworska; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. LÄS MER

  4. 3. What limits the luminosity of red supergiants?

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

    Författare :Eric Svensson; [2023]
    Nyckelord :Stellar evolution; Red supergiants; Red giants; Luminosity; Binary stars; Binary star systems; Binary star interactions; Binary stellar evolution; Humphreys-Davidson limit; Upper luminosity limit; BSE; Population synthesis; Simulations; M31; LMC; SMC; Metallicity; Mass transfer; Merging; Physics and Astronomy;

    Sammanfattning : The observed upper limit of the luminosity of red supergiants, often called the Humphreys-Davidson limit, has recently been shown to be independent of metallicity and to not be explainable by single star evolution – findings that both contradict established ideas of the origins of the limit. It is now known that the vast majority of stars with sufficient mass to possibly evolve into red supergiants above the limit interact with companion stars at some point during their lives. LÄS MER

  5. 4. Svenska gymnasieelevers uppfattningar om storlek och avstånd i universum

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för utbildningsvetenskap

    Författare :Karolin Nilsson; [2023]
    Nyckelord :Astronomy; Misconceptions; Educational Research; Science Education; High School Students; Physics and Astronomy;

    Sammanfattning : This study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and alternative conceptions they hold.

  7. 5. Aurora-Imaging UAV Cameras

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

    Författare :Benjamin Girchman; Joel Widén; [2023]
    Nyckelord :;

    Sammanfattning : Ground based optical observations are limited by weather. One of the possible solutions is using adrone to fly above the clouds. This enables new approaches when planning experiments. The aim ofthis project is to produce and evaluate prototypes of aurora-imaging cameras that will be placed insideof such a drone. LÄS MER
