On the progenitor and supernova of the sn 2002cx-like supernova 2008ge
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 ...
DISAPPEARANCE OF THE PROGENITOR OF SUPERNOVA iPTF13bvn
(IOP PUBLISHING, 2016-07)
Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observations ...
SNhunt151: An explosive event inside a dense cocoon
(Oxford University Press, 2018-04)
SNhunt151 was initially classified as a supernova (SN) impostor (nonterminal outburst of a massive star). It exhibited a slow increase in luminosity, lasting about 450 d, followed by a major brightening that reaches M V ≈ ...
The Type IIn Supernova SN 2010bt: The Explosion of a Star in Outburst
(Institute of Physics Publishing, 2018)
It is well known that massive stars (M > 8 M ) evolve up to the collapse of the stellar core, resulting in most cases in a supernova (SN) explosion. Their heterogeneity is related mainly to different configurations of the ...
