Constraining hydrodynamic model of nearby type IIP SN 2023ixf
V. P. Utrobin, N. N. Chugai
Despite proximity of SN 2023ixf and a wealth of observational data, the released hydrodynamic models leave too broad range of the derived explosion energy and the ejected mass. We…
Southern eROSITA bubble as a forward shock and the low-metallicity CGM. South-east side story
E. Churazov, I. I. Khabibullin, A. M. Bykov +4
Unlike the complicated X-ray and radio structure observed in the North Polar Spur area, the South-Eastern part of the eROSITA bubbles can be reasonably well described as a propagat…
Type IIP SN 2024bch: Hydrodynamic model, shock breakout, and circumstellar interaction
V. P. Utrobin, N. N. Chugai
The well-observed type IIP SN 2024bch with the short plateau is shown to be an outcome of the red supergiant explosion with the presupernova mass of 14-15 Msun, the explosion energ…
Puzzle of [Ar II] 7 mcm line broad component of SN 1987A
Nikolai N. Chugai, Victor P. Utrobin
We explore the origin of the broad component of the [Ar II] 7 mcm line emission related to the ejecta excitation by the neutron star of SN 1987A. We argue that the line broad wings…
Revisiting short-plateau SN 2018gj
V. P. Utrobin, N. N. Chugai
We present an alternative model of unusual type-IIP SN 2018gj. Despite the short plateau and early gamma-rays escape seeming to favor low-mass ejecta, our hydrodynamic model requir…
Origin of broad He II 4686Å emission in early spectra of type IIP supernovae
Nikolai Chugai, Victor Utrobin
We propose a model for the origin of the broad He II 4686A emission in the early spectrum of type II SN~2020jfo. The 4686A line is emitted presumably by dense fragments embedded in…
