11. Studies of late-type stars and massive star formation regions using masers
Sammanfattning : .... LÄS MER
12. On the Chemical Composition of Metal-Poor Stars : Impact of Stellar Granulation and Departures from Local Thermodynamic Equilibrium on the Formation of Spectral Lines
Sammanfattning : The information about the chemical compositions of stars is encoded in their spectra. Accurate determinations of these compositions are crucial for our understanding of stellar nucleosynthesis and Galactic chemical evolution. LÄS MER
13. Infrared spectroscopic investigations of stellar winds from red giants
Sammanfattning : .... LÄS MER
14. Clues to galaxy evolution from spectroscopic observations of Galactic centre stars
Sammanfattning : In this work we present results from spectroscopic observations of Galactic centre stars. High resolution stellar spectroscopy can be used to determine accurate stellar metallicities and abundances. Observing stars in the Galactic centre is challenging due to extreme extinction. LÄS MER
15. Photoelectric broad- and narrowband photometry of bright early- and late-type stars, with a discussion of their absolute magnitudes and intrinsic colours
