  2. 1. Solar access indicators for urban planning

    Author : Agnieszka Czachura; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar access; urban planning; performance indicator; daylighting; sunlighting; neighbourhood; metric taxonomy; urban density;

    Abstract : Solar access describes the amount and distribution of sunlight in living environments. Access to sunlight is crucial for the health and sustainability of cities. It is vital for people and vegetation, and for energy production and conservation. READ MORE

  4. 2. The origin and chemical evolution of iron-peak and neutron-capture elements in the Milky Way disk

    Author : Chiara Battistini; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: abundances; Stars: solar-type; Galaxy: disk; Galaxy: evolution; Galaxy: solar neighbourhood;

    Abstract : All the elements heavier than Li are created during stellar evolution. Even if our knowledge of this process is good, many questions still remain. READ MORE

  5. 3. Galactic Structure Revealed by Space Astrometry

    Author : Johan Holmberg; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomi; cosmic chemistry; Galactic structure; Milky Way Galaxy; Galactic kinematics and dynamics; Galactic chemical evolution; moving groups; solar neighbourhood; dark matter; astrometry; Hipparcos; space research; Astronomy; rymdvetenskap; kosmisk kemi; Space technology; Rymdteknik; Fysicumarkivet A:2001:Holmberg;

    Abstract : This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically.

  6. 4. The nature of stars with a common origin: clues from metallicity, elemental abundances, and kinematics

    Author : Cheng Liu; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: abundances; Galaxy: evolution; Galaxy: solar neighbourhood; Galaxy: bulge; Galaxy: globular clusters;

    Abstract : Most of field stars originate from dissolved star clusters. If the gas cloud is well mixed the stars in the cluster are expected to be chemically homogenous. READ MORE

  7. 5. Dark Matter in the Solar System, Galaxy, and Beyond

    Author : Axel Widmark; Jens Jasche; Malcolm Fairbairn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter: phenomenology; dark matter: indirect detection; dark matter: particle nature; Galactic dynamics; Galactic composition; Theoretical Physics; teoretisk fysik;

    Abstract : There is evidence that dark matter constitutes a majority of the Universe's matter content. Yet, we are ignorant about its nature. Understanding dark matter requires new physics, possibly in the form of a new species of fundamental particles. READ MORE
