  1. 1. High Resolution Observations of Masers

    Author : Jiyune Yi; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cosmic masers are associated with both the early and late stages in the life of a star. High resolution observations of maser emissions are unique tools to study the physical and chemical environments in and around young stellar and protostellar objects, and around stars at the end of their life.

  2. 2. A quantum-chemical study to the magnetic characteristics of methanol and its applications in astronomy

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Boy Lankhaar; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methanol; maser polarization; star formation; magnetic fields; masers;

    Abstract : Magnetic fields play an important role during star formation. Direct magnetic field strength observations have proven specifically challenging in the dynamic protostellar phase. READ MORE

  3. 3. Methanol masers reveal the magnetic field of a high mass protostar

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Daria Dall` Olio; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic field – stars: formation – stars: massive – masers – polarization – stars: individual: IRAS 18089-1732;

    Abstract : 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.

  4. 4. Methanol Masers as Signposts of Star Formation and VLBI Observations of Coronal Emission from Young Stars

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Michele Pestalozzi; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Using a consistent survey of the galactic plane at 6.7 GHz as a starting point, this thesis reports on the observational as well as theoretical results achieved by extensively studying of the phenomenon of class II methanol masers. The general catalogue of 6. READ MORE
