Supernova 1987A: 3D Mixing and light curves for explosion models based on binary-merger progenitors
V. P. Utrobin, A. Wongwathanarat, H. -Th. Janka +4
Six binary-merger progenitors of Supernova 1987A (SN 1987A) with properties close to those of the blue supergiant Sanduleak -69 202 are exploded by neutrino heating and evolved unt…
Three-dimensional mixing and light curves: constraints on the progenitor of supernova 1987A
Victor Utrobin, Annop Wongwathanarat, H. -Thomas Janka +3
With the same method as used previously, we investigate neutrino-driven explosions of a larger sample of blue supergiant models. The larger sample includes three new presupernova s…
A young contracting white dwarf in the peculiar binary HD 49798/RX J0648.0--4418?
S. B. Popov, S. Mereghetti, S. I. Blinnikov +2
HD 49798/RX J0648.0--4418 is a peculiar X-ray binary with a hot subdwarf (sdO) mass donor. The nature of the accreting compact object is not known, but its spin period ~s a…
Luminous type IIP SN 2013ej with high-velocity Ni-56 ejecta
V. P. Utrobin, N. N. Chugai
We explore the well-observed type IIP SN 2013ej with peculiar luminosity evolution. It is found that the hydrodynamic model cannot reproduce in detail the bolometric luminosity at…
Modeling of the Interaction of GRB Prompt Emission with the Circumburst Medium
D. A. Badjin, S. I. Blinnikov, K. A. Postnov
We present methodology and results of numerical modeling of the interaction of GRB prompt emission with the circumburst medium using a modified version of the multi-group radiation…
