Possible evidence of asymmetry in SN 2007rt, a type IIn supernova
(EDP SCIENCES S A, 2009)
An optical photometric and spectroscopic analysis of the slowly-evolving type IIn SN 2007rt is presented, covering a duration of 481 days after discovery. Its earliest spectrum, taken approximately 100 days after the ...
Nebular phase observations of the type-Ib supernova iPTF13bvn favour a binary progenitor
(EDP Sciences, 2015)
Aims. We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done similar to 300 days after the explosion. We discuss them in the ...
On the progenitor and supernova of the sn 2002cx-like supernova 2008ge
(2010)
We present observations of supernova (SN) 2008ge, which is spectroscopically similar to the peculiar
SN 2002cx, and its pre-explosion site that indicate that its progenitor was probably a white dwarf.
NGC 1527, the host ...
Type IIP supernova light curves affected by the acceleration of red supergiant winds
(Oxford University Press, 2018)
We introduce the first synthetic light-curve model set of Type IIP supernovae exploded within circumstellar media in which the acceleration of the red supergiant winds is taken into account. Because wind acceleration makes ...
Supernova progenitors, their variability and the Type IIP Supernova ASASSN-16fq in M66
(OXFORD UNIV PRESS, 2017)
We identify a pre-explosion counterpart to the nearby Type IIP supernova ASASSN-16fq (SN 2016cok) in archival Hubble Space Telescope data. The source appears to be a blend of several stars that prevents obtaining accurate ...
