1. Solar access indicators for urban planning
Sammanfattning : 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. LÄS MER
2. The origin and chemical evolution of iron-peak and neutron-capture elements in the Milky Way disk
Sammanfattning : All the elements heavier than Li are created during stellar evolution. Even if our knowledge of this process is good, many questions still remain. LÄS MER
3. Galactic Structure Revealed by Space Astrometry
Sammanfattning : 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. LÄS MER
4. The nature of stars with a common origin: clues from metallicity, elemental abundances, and kinematics
Sammanfattning : 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. LÄS MER
5. Dark Matter in the Solar System, Galaxy, and Beyond
Sammanfattning : 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. LÄS MER
