Hydrodynamic instabilities in long-term three-dimensional simulations of neutrino-driven supernovae of 13 red supergiant progenitors
Beatrice Giudici, Michael Gabler, Hans-Thomas Janka
We present long-term three-dimensional (3D) simulations of Type-IIP supernovae (SNe) for 13 non-rotating, single-star, red-supergiant (RSG) progenitors with zero-age-main-sequence…
Magnetorotational supernovae: A nucleosynthetic analysis of sophisticated 3D models
Moritz Reichert, Martin Obergaulinger, Miguel-Angel Aloy +3
Magnetorotational supernovae are a rare type of core-collapse supernovae where the magnetic field and rotation play a central role in the dynamics of the explosion. We present the…
The infancy of core-collapse supernova remnants
Michael Gabler, Annop Wongwathanarat, Hans-Thomas Janka
We present 3D hydrodynamic simulations of neutrino-driven supernovae (SNe) with the PROMETHEUS-HOTB code, evolving the asymmetrically expanding ejecta from shock breakout until the…
Three-dimensional Models of Core-collapse Supernovae From Low-mass Progenitors With Implications for Crab
G. Stockinger, H. -Th. Janka, D. Kresse +9
We present 3D full-sphere supernova simulations of non-rotating low-mass (~9 Msun) progenitors, covering the entire evolution from core collapse through bounce and shock revival, t…
High angular resolution ALMA images of dust and molecules in the SN 1987A ejecta
Phil Cigan, Mikako Matsuura, Haley L. Gomez +23
We present high angular resolution (~80 mas) ALMA continuum images of the SN 1987A system, together with CO =2 1, =6 5, and SiO =5 $\!\…
X-Ray and Gamma-Ray Emission From Core-collapse Supernovae: Comparison of Three-dimensional Neutrino-driven Explosions With SN 1987A
Dennis Alp, Josefin Larsson, Keiichi Maeda +7
During the first few hundred days after the explosion, core-collapse supernovae (SNe) emit down-scattered X-rays and gamma-rays originating from radioactive line emissions, primari…
X-ray Absorption in Young Core-Collapse Supernova Remnants
Dennis Alp, Josefin Larsson, Claes Fransson +3
The material expelled by core-collapse supernova (SN) explosions absorbs X-rays from the central regions. We use SN models based on three-dimensional neutrino-driven explosions to…
The 30-Year Search for the Compact Object in SN 1987A
Dennis Alp, Josefin Larsson, Claes Fransson +32
Despite more than 30 years of searches, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimet…
Constraining properties of high-density matter in neutron stars with magneto-elastic oscillations
Michael Gabler, Pablo Cerdá-Durán, Nikolaos Stergioulas +2
We discuss torsional oscillations of highly magnetised neutron stars (magnetars) using two-dimensional, magneto-elastic-hydrodynamical simulations. Our model is able to explain bot…
