1. Satellite and ground based observations of massive star forming regions
Abstract : Results from submm/mm radio astronomical observations, using the astronomy/-aeronomy satellite Odin and the 20m telescope at the Onsala Space Observatory, are presented. Analysis of spectroscopic data of interstellar rotational emission lines from gaseous H2O residing in giant molecular clouds (GMCs), reveal important new clues about the chemistry and spatial distribution of water molecules in these regions, including estimates of the water abundance in molecular outflows associated with massive star formation.

2. Water in molecular outflows and shocks: Studies with Odin and Herschel
Abstract : This thesis describes observations and analyses of water in molecular outflows from young stellar objects. The abundance of this molecule (with respect to molecular hy- drogen) is deduced from observations carried out with primarily the Odin and Herschel telescopes. READ MORE

3. Companion wind shaping in binaries involving an AGB star
Abstract : Stars of initial masses between 0.8-8 M☉ will become "asymptotic giant branch" (AGB) stars during the final stages of their evolution. During this phase, the stars are characterized by low velocity and high-density winds. READ MORE
