    Author : Roberts Fisers; [2022]
    Keywords : Galaxy; encounter; SPH; NSC; Physics and Astronomy;

    Abstract : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. READ MORE

  3. 2. Method development for a tribological diffusion couple of rock and cemented carbide
