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…

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…
The circumstellar material around the Type IIP SN 2021yja
Alexandra Kozyreva, Jakub Klencki, Alexei V. Filippenko +4
The majority of Type II-plateau supernovae (SNe IIP) have light curves that are not compatible with the explosions of stars in a vacuum; instead, the light curves require the proge…
Low-luminosity type IIP supernovae: SN 2005cs and SN 2020cxd as very low-energy iron core-collapse explosions
Alexandra Kozyreva, Hans-Thomas Janka, Daniel Kresse +2
SN 2020cxd is a representative of the family of low-energy, underluminous Type IIP supernovae (SNe), whose observations and analysis were recently reported by Yang et al. (2021). H…
Synthetic observables for electron-capture supernovae and low-mass core collapse supernovae
Alexandra Kozyreva, Petr Baklanov, Samuel Jones +2
Stars in the mass range from 8 to 10 solar masses are expected to produce one of two types of supernovae (SNe), either electron-capture supernovae (ECSNe) or core-collapse supernov…
Parameters of the type-IIP supernova SN 2012aw
A. A. Nikiforova, P. V. Baklanov, S. I. Blinnikov +7
We present the results the photometric observations of the Type IIP supernova SN 2012aw obtained for the time interval from 7 till 371 days after the explosion. Using the previousl…
The influence of line opacity treatment in STELLA on supernova light curves
Alexandra Kozyreva, Luke Shingles, Alexey Mironov +2
We systematically explore the effect of the treatment of line opacity on supernova light curves. We find that it is important to consider line opacity for both scattering and absor…
A Model for Fast Blue Optical Transient AT2018Cow: Circumstellar Interaction of a Pulsational Pair-instability Supernova
Shing-Chi Leung, Sergei Blinnikov, Ken'ichi Nomoto +3
The Fast Blue Optical Transient (FBOT) ATLAS18qqn (AT2018cow) has a light curve as bright as superluminous supernovae but rises and falls much faster. We model this light curve by…
Strongly lensed SN Refsdal: refining time delays based on the supernova explosion models
Petr Baklanov, Natalia Lyskova, Sergei Blinnikov +1
We explore the properties of supernova (SN) "Refsdal" - the first discovered gravitationally lensed SN with multiple images. A large magnification provided by the galactic-scale le…
Shock breakouts from red supergiants: analytical and numerical predictions
Alexandra Kozyreva, Ehud Nakar, Roni Waldman +2
Shock breakout (SBO) signal is the first signature of the supernova explosion apart from gravitational waves and neutrinos. Observational properties of SBO, such as bolometric lumi…

We present UBVRI photometry of the supernova 2017eaw in NGC 6946, obtained in the period from May 14 until December 7, 2017. We derive dates and magnitudes of maximum light in the…
Quark deconfinement as supernova explosion engine for massive blue-supergiant stars
