Nucleosynthesis in magneto-rotational supernovae
Moritz Reichert, Martin Obergaulinger, Marius Eichler +2
We present the nucleosynthesis of magneto-rotational supernovae (MR-SNe) including neutrino-driven and magneto-rotational-driven ejecta based, for the first time, on 2D simulations…
Low Energy measurement of the reaction cross section and its impact on weak r-process nucleosynthesis
G. G. Kiss, T. N. Szegedi, P. Mohr +4
Lighter heavy elements beyond iron and up to around silver can form in neutrino-driven ejecta in core-collapse supernovae and neutron star mergers. Slightly neutron-rich conditions…
129I and 247Cm in Meteorites Constrain the Last Astrophysical Source of Solar r-process Elements
Benoit Côté, Marius Eichler, Andrés Yagüe +12
The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron-capture process (r process), but the ast…
Magnetorotational Explosion of A Massive Star Supported by Neutrino Heating in General Relativistic Three Dimensional Simulations
Takami Kuroda, Almudena Arcones, Tomoya Takiwaki +1
We present results of three-dimensional (3D), radiation-magnetohydrodynamics (MHD) simulations of core-collapse supernovae in full general relativity (GR) with spectral neutrino tr…
Nuclear physics uncertainties in neutrino-driven, neutron-rich supernova ejecta
J. Bliss, A. Arcones, F. Montes +1
Neutrino-driven ejecta in core collapse supernovae (CCSNe) offer an interesting astrophysical scenario where lighter heavy elements between Sr and Ag can be synthesized. Previous s…
Nucleosynthesis of "Light" Heavy Nuclei in Neutrino-driven Winds. Role of () reactions
Jorge Pereira, Almudena Arcones, Julia Bliss +1
Neutrino-driven winds following core collapse supernovae have been proposed as a suitable site where the so-called light heavy elements (between Sr to Ag) can be synthetized. For m…
