    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binary Bose-Einstein condensates in ultracold gases; hydrodynamics; quantum turbulence; neutron stars; the inner crust; nuclear astrophysics; fysik; Physics;

    Sammanfattning : In the present thesis, “Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars”, the hydrodynamic effects, instabilities and superfluid turbulence in binary immiscible ultracold gases, and hydro-elastic macroscopic coupled modes and microscopic structure of the inner layers of the crust of neutron stars, are studied. The ultracold gas dynamics can be realized in the laboratory. LÄS MER

  4. 3. The Advanced Spectral Leakage (ASL) scheme for simulations of merging neutron stars

    Författare :Davide Gizzi; Stephan Rosswog; Evan O'Connor; Albino Perego; Carla Fröhlich; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrodynamics; radiative transfer; neutrinos; stars: neutron; supernovae: general; Astronomy; astronomi;

    Sammanfattning : The detection of a blue macronova following the event GW170817 has emphasized the role that neutrinos play in merging neutron stars. In particular, neutrinos are able to drive mass ejection, the so-called neutrino-driven winds, and change the neutron richness of the matter by absorption. LÄS MER

  5. 4. Survey Astronomy with the LSST and Multimessenger Synergies

    Författare :Christian Setzer; Hiranya Peiris; Jens Jasche; Evan O'Connor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; binary neutron stars; gravitational waves; LSST; fysik; Physics;

    Sammanfattning : Survey astronomy has become a powerful tool for discoveries in astrophysics and cosmology. In the coming years this approach will be taken even further with the start of the ten year survey of the Large Synoptic Survey Telescope. LÄS MER

  7. 5. Modelling and Detecting Kilonovae in the Rubin Observatory Era

    Författare :Christian N. Setzer; Hiranya Peiris; Jens Jasche; Stephen Smartt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmology; transient surveys; kilonovae; neutron stars; population modelling; Physics; fysik;

    Sammanfattning : Survey astronomy is a powerful tool for discoveries in astrophysics and cosmology. In the coming years, this field will be revolutionised with the start of the ten-year Legacy Survey of Space and Time (LSST), to be conducted at the Vera C. Rubin Observatory. LÄS MER
