  1. 1. PTF12os and iPTF13bvn : Two stripped-envelope supernovae discovered by the Palomar Transient Factory

    Författare :Christoffer Fremling; Jesper Sollerman; Ross Church; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sovernovae;

    Sammanfattning : This thesis is based on research made by the intermediate Palomar Transient Factory [(i)PTF], and it is particularly closely tied to the still ongoing research on the stripped-envelope (SE) supernova (SN), iPTF13bvn (Type Ib), that occurred in the nearby galaxy NGC 5806. This SN was initially thought to have been the explosion of a very massive Wolf-Rayet (WR) star, but I have shown that this is very likely not the case. LÄS MER

  3. 2. Stripped-envelope supernovae discovered by the Palomar Transient Factory

    Sammanfattning : This thesis is based on research made by the intermediate Palomar Transient Factory [(i)PTF]. The focus is on stripped-envelope (SE) supernovae (SNe) discovered by (i)PTF, and it is closely tied to the research on the SE SN iPTF13bvn, that occurred in the nearby galaxy NGC 5806. LÄS MER
