    Abstract : This thesis is based on four papers dealing with various aspects of interactions in binary stars. Interactions between stars occur at nearly all stages of their evolution and can take many forms. READ MORE

  5. 3. Stellar Models in General Relativity

    Author : Lars Samuelsson; Kjell Rosquist; Brandon Carter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General relativity; compact objects; neutron stars; Physics; Fysik;

    Abstract : Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. READ MORE

  6. 4. Jet-wind interaction in neutron star mergers

    Author : Lorenzo Nativi; Stephan Rosswog; Jesper Sollerman; Felix Ryde; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; jets; kilonova; macronova; gamma-ray burst; neutron star merger; compact objects; Astronomy; astronomi;

    Abstract : Besides being sources of gravitational waves, there has been evidence that neutron starmergers release neutron-rich material suitable for the production of heavy r-process nuclei.The radioactive decay of these freshly synthesised elements powers a rapidly evolvingthermal transient, the “macronova” (also known as “kilonova”).

  7. 5. On various aspects of extended objects

    Author : Mariusz Hynek; Jens Hoppe; Volker Bach; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : This thesis concerns classical and quantum aspects of minimal manifolds embedded in flat Minkowski space. In particular, we study the Lie algebra of diffeomorphisms on 2 dimensional compact manifolds as well as discuss singularity formation for relativistic minimal surfaces in co-dimension one. READ MORE
