1. 1. Bumpy light curves of interacting supernovae

   Författare :Anders Nyholm; Jesper Sollerman; Peter Lundqvist; Nils Ryde; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iPTF13z; supernova; SN; circumstellar medium; CSM; SN Type IIn; intermediate Palomar Transient Factory; iPTF; Astronomy; astronomi;

   Sammanfattning : A supernova (SN) is the explosive destruction of a star. Via a luminous outpouring of radiation, the SN can rival the brightness of its SN host galaxy for months or years. LÄS MER

3. 2. Supernova surroundings on circumstellar and galactic scales

   Författare :Anders Nyholm; Jesper Sollerman; Peter Lundqvist; Philip James; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supernovae; circumstellar medium; SNe Type IIn; iPTF13z; intermediate Palomar Transient Factory; active galactic nuclei; SN 2014J; Astronomy; astronomi;

   Sammanfattning : Some stars cease to be in a bright and destructive display called a supernova. This thesis explores what we can learn about supernovae (SNe) by studying their immediate surroundings, and what the SNe can teach us about their environments. LÄS MER

4. 3. X-ray emission from supernova shock waves

   Författare :Tanja Nymark; Claes Fransson; Cecilia Kozma; Jacco Vink; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

   Sammanfattning : A theoretical study of the interaction between supernovae and their surroundings is presented.Supernovae are the endpoint of the life of massive stars, and are the dominant contributors to the chemical evolution of the Universe. During its life a massive star greatly modifies its environment. LÄS MER
