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

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  3. 2. Capture into mean motion resonance

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Kaltrina Kajtazi; [2021]
    Keywords : MMR; Mean motion resonance; Planetary dynamics; First order MMR; Numerical integration with N-body; Physics and Astronomy;

    Abstract : Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. READ MORE

  4. 3. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Colin Carlile; [2021]
    Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

    Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

  5. 4. The detectability of single- and multiple-planet systems in Gaia data

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Martin Gustavsson; [2015]
    Keywords : Gaia; Astrometry; Exoplanets; Orbit-fitting; Physics and Astronomy;

    Abstract : The all-sky survey of Gaia will generate vast amounts of astrometric data, in which there are expected to be thousands of planets found. Finding a system of $n_\textup{p}$ planets requires fitting of a total $5+7n_\textup{p}$ parameters: five astrometric and seven Keplerian parameters for every planet. READ MORE

  6. 5. Space Rewritten - an exploration of spaces at the Tycho Brahe Museum

    University essay from Lunds universitet/Avdelningen för konsthistoria och visuella studier

    Author : Anna Molin; [2014]
    Keywords : Economic Space; Simulacra; The Tycho Brahe Museum; Mythic and theoretical Space; Ernst Cassirer; Aesthetic; Arts and Architecture;

    Abstract : In this thesis I use the text Mythic, Aesthetic and Theoretical space by Ernst Cassirer to reflect on the Tycho Brahe Museum, Ven. Questions asked, are if conflicting spaces can be seen at the site and if one space can subjugate another. It is also discussed if there exist other spaces than mythic, aesthetic and theoretical.
