  4. 2. Chemical Abundance Analysis of Population II Stars The Summary Includes a Background in General Astronomy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Jonsell; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomy; Galactic evolution; Halo; Milky Way; Oxygen; r-element; s-element; Stellar abundances; Astronomi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik;

    Abstract : We are made of stardust in the sense that most atomic nuclei around us have been formed by stars. Stars synthesise new elements and expel them to the interstellar medium, from which later new generations of stars are born. We can map this chemical evolution by analysing the atmospheric contents of old Galactic halo stars. READ MORE

  5. 3. Gas Production in Distant Comets

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marcus Gunnarsson; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Comets; Radio Astronomy; Molecular Spectroscopy; Coma Models; Astronomi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik; astronomi; Astronomy;

    Abstract : Molecular spectroscopy at radio wavelengths is a tool well suited for studying the composition and outgassing kinematics of cometary comae. This is particularly true for distant comets, i.e. comets at heliocentric distances greater than a few AU, where the excitation of molecules is inefficient other than for rotational energy levels.

  6. 4. Methods of Multi-Conjugate Adaptive Optics for Astronomy

    University dissertation from Lund Observatory, Lund University

    Author : Ralf Flicker; Lunds universitet.; Lund University.; [2003]

    Abstract : Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.

  7. 5. Reaching for the Stars : Studies in the History of Swedish Stellar and Nebular Astronomy, 1860–1940

    University dissertation from History of Science and Ideas

    Author : Gustav Holmberg; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1999]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; stellar astronomy; history of astronomy; astrophysics; history of modern Swedish science; scientific practice; Astronomy; Astronomi;

    Abstract : This study considers astrophysics, stellar and nebular astronomy in Sweden. Emphasis is on the role of scientific technologies and practice, and the emergence of a modern observational astronomy, supplanting classical astronomy as the most vital field of Swedish astronomy. READ MORE
