1. A quantum-chemical study to the magnetic characteristics of methanol and its applications in astronomy
Sammanfattning : Magnetic fields play an important role during star formation. Direct magnetic field strength observations have proven specifically challenging in the dynamic protostellar phase. LÄS MER
2. Methanol masers reveal the magnetic field of a high mass protostar
Sammanfattning : The role played by magnetic fields in high-mass star formation is not yet fully clear. Theoretical simulations have shown that magnetic fields appear to suppress fragmenta- tion in the star forming cloud, to enhance accretion via disc and to provide feedback in the form of outflows and jets. LÄS MER
3. Magnetic fields around massive protostars as traced by masers and dust emission
Sammanfattning : It is not fully clear how the magnetic field acts during the first stages of star formation. A possible way to clarify its role is to observe the polarized light coming from masers and thermal dust emission. LÄS MER
4. Tracing cosmic magnetic fields using molecules
Sammanfattning : Understanding the magnetic field strength and morphology of astrophysical regions is of great importance to understand their dynamics. There exist a number of methods astronomers can employ to trace magnetic field structures, and each have their own limitations. This thesis focuses on tracing magnetic field using molecules. LÄS MER
