3D insights into SN 1987A: ALMA observations compared to hydrodynamical explosion simulations
R. Wesson, M. Gabler, M. Lyons +9
We obtain three-dimensional distributions of CO and SiO molecules from high spatial resolution (0.03--0.06") ALMA observations of SN 1987A at two different epochs. The evolution be…

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…

Tracing the ejecta structure of SN 1987A: Insights and diagnostics from 3D MHD simulations
S. Orlando, M. Miceli, M. Ono +14
Supernova (SN) 1987A provides a unique window into the aftermath of a massive stellar explosion, offering key insights into the ejecta's morphology, composition, explosion mechanis…
