    Keywords : HUMANIORA; HUMANITIES; Frontispiece; illustrated title page; astronomy; 17th century; allegory; engraving; illustrated book; HUMANITIES and RELIGION Aesthetic subjects Art; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Konstvetenskap; konstvetenskap; Art History;

    Abstract : The thesis is a survey of 291 frontispieces and illustrated title pages in European books on astronomy from the 17th century. It is a quantitative and qualitative survey of how motifs are related to consumption, identification and display. READ MORE

  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; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adaptive optics; anisoplanatism; laser guide stars; performance estimation; wavefront reconstruction; extremely large telescopes; optics; Electromagnetism; Elektromagnetism; acoustics; Astronomy; akustik; space research; optik; multi-conjugate; cosmic chemistry; Astronomi; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:2003:Flicker;

    Abstract : This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future.

  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; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [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
