1. Mass Loss of Evolved Stars : Improving Mass-Loss Rates and Distances
Sammanfattning : In the final stages of their lives, low to intermediate-mass stars enter the Asymptotic Giant Branch (AGB) phase, where they experience significant mass loss through dusty stellar winds. This mass loss is pivotal, not only for the chemical enrichment of the interstellar medium, setting the stage for new stars and planets to form, but also in dictating the evolution and the ultimate fate of the stars themselves.

2. Metallicity determination of M dwarfs
Sammanfattning : M dwarfs constitute around 70% of all stars in the local Galaxy. Their multitude together with their long main-sequence lifetimes make them important for studies of global properties of the Galaxy such as the initial mass function or the structure and kinematics of stellar populations.

3. Characterization and analysis of the astrometric errors in the global astrometric solution for Gaia
Sammanfattning : The space astrometry mission Gaia, planned for launch in 2013 by the European Space Agency (ESA), will provide the most comprehensive and accurate catalogue of astrometric data for galactic and astrophysical research in the coming decades. It will observe roughly one billion stars, quasars and other point like objects for which the five astrometric parameters (position, parallax and proper motion) will be determined. LÄS MER
4. Intima samhällsvisioner : Sporten mellan minimalism och gigantism
Sammanfattning : Ambitions and ClarificationsThe book takes its point of departure in the "intimate visions of society" that are significant of contemporary social life. This concept refers to the tendency to apprehend good social relations as personal, close and warm, while bad relations correspondingly are perceived as impersonal, cold, distant and alienated.
