  1. 6. Search for transiting exoplanets in globular clusters

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

    Författare :Oskar Nilsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. LÄS MER

  3. 7. Combining Hipparcos and Gaia data: Improved Astrometric Calculations With Orvara

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

    Författare :Melvin Tham; [2023]
    Nyckelord :Astrometry; Af Leporis; Smethells 119; Gliese 105; Gliese 86; Orvara; Hipparcos; Gaia; Physics and Astronomy;

    Sammanfattning : Hipparcos and Gaia are two missions intended to catalogue positions and motions of stellar objects. Orvara is a computer program which aims to combine the data from these two missions to calculate Keplerian parameters for stellar systems. LÄS MER

  4. 8. En grön studie om konsumentens ekologiska köpbeslut : En kvantitativ studie om faktorer som påverkar konsumentens köpbeslut gällande ekologiska produkter

    Kandidat-uppsats, Södertörns högskola

    Författare :Rita Jamil; Kristaps Kajins; [2022]
    Nyckelord :Consumer behaviour; purchase decision; sustainable consumption; ecological; environment; organic products; Konsumentbeteende; köpbeslut; hållbar konsumtion; ekologisk; miljö; ekologisk konsumtion; ekologiska produkter.Konsumentbeteende; köpbeslut; hållbar konsumtion; ekologisk; miljö; ekologisk konsumtion; ekologiska produkter;

    Sammanfattning : Klimatförändringar beskrivs som en av vår tids största utmaningar. Mänskligheten konsumerar för 1,6 planeter och i Sverige konsumeras det som att vi har tillgång till fyra planeter. Tidigare forskning visar på att medvetenheten kring problematiken har ökat, men där konsumentens kunskap och faktiska agerande inte går hand i hand. LÄS MER

  5. 9. Detecting Transiting Exoplanets in Crowded Fields

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Eddie Larsson; [2022]
    Nyckelord :Transit method; Globular cluster; crowded environments; exoplanets; transiting exoplanets; Physics and Astronomy;

    Sammanfattning : The first planet orbiting a main-sequence star was discovered in 1995. Since then more than 4000 additional exoplanets have been discovered. This is a rapidly evolving field in astrophysics. One of the most common ways to detect an exoplanet is through transit, as the brightness of the host star decreases. LÄS MER

  7. 10. Climate Simulations of an Exoplanet with a Slab Ocean: A 3D Model Intercomparison of various GCMs

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

    Författare :Moa Biserud; [2022]
    Nyckelord :Climate simulations; GCM; ROCKE-3D; Exoplanet; Slab Ocean; Qflux=0;

    Sammanfattning : Three-dimensional (3D) planetary general circulation models (GCMs) have been derived from global climate models used to project 21st century changes in Earth's climate. GCMs are used to address questions regarding the climate-and habitability aspects of terrestrial planets within the solar system and assess the habitability of planets outside of the solar system, so called exoplanets.
