Helium superluminous SN 2021bnw : an explosion of a massive star with a pre-outburst
Alexandra Kozyreva, Matteo Bugli, Alexey Mironov +1
Superluminous supernovae (SLSNe) remain an intriguing topic in supernova (SN) transient astronomy. While the majority of SLSNe are shown to be explained by energy streaming from th…
The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases
A. Fiore, A. Kozyreva, L. Yan +40
Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…
SN 2023ixf -- an average-energy explosion with circumstellar medium and a precursor
Alexandra Kozyreva, Andrea Caputo, Petr Baklanov +2
Abridged: The fortunate proximity of the SN2023ixf allowed astronomers to follow its evolution from almost the moment of the collapse of the progenitor's core. SN2023ixf can be exp…
Primary and secondary source of energy in the superluminous supernova 2018ibb
Alexandra Kozyreva, Luke Shingles, Petr Baklanov +2
We examine the pair-instability origin of superluminous supernova 2018ibb. As the base model, we use a non-rotating stellar model with an initial mass of 250 Msun at about 1/15 sol…
Thermonuclear explosions as Type II supernovae
Alexandra Kozyreva, Javier Moran-Fraile, Alexander Holas +5
We consider a binary stellar system, in which a low-mass, of 0.6 Msun, carbon-oxygen white dwarf (WD) mergers with a degenerate helium core of 0.4 Msun of a red giant. We analyse t…
