1. 1. Spectral modeling of nebular-phase supernovae

   Författare :Anders Jerkstrand; Claes Fransson; Luc Dessart; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; nucleosynthesis; radiative transfer; massive stars; 1987A; IIP; supernovor; nukleosyntes; spektralmodellering; strålningstransport; massiva stjärnor; 1987A; IIP; Astronomy; astronomi;

   Sammanfattning : Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). LÄS MER

3. 2. Non-Local Thermodynamic Equilibrium Spectral Modelling of Kilonovae

   Författare :Quentin Pognan; Anders Jerkstrand; Kyohei Kawaguchi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transients: Neutron Star Mergers; Radiative Transfer; Astronomy; astronomi;

   Sammanfattning : The astrophysical origin of rapid neutron capture (r-process) elements has long remained a puzzle and been the object of scientific debate. Neutron star (NS) mergers have historically been suggested as an ideal site for the creation of these elements, and were propelled into focus following the detection of the first binary neutron star (BNS) merger in 2017.
