Effects of neutrino oscillations on nucleosynthesis and neutrino signals for an 18 M supernova model

Meng-Ru Wu, Yong-Zhong Qian, Gabriel Martinez-Pinedo +2

In this paper, we explore the effects of neutrino flavor oscillations on supernova nucleosynthesis and on the neutrino signals. Our study is based on detailed information about the…

The Role of Fission in Neutron Star Mergers and its Impact on the r-Process Peaks

Marius Eichler, Almudena Arcones, Alexandra Kelic +10

Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations can scrutinize two aspects: (a) the conditions in the astr…

On the nuclear robustness of the r process in neutron-star mergers

Joel de Jesús Mendoza-Temis, Meng-Ru Wu, Karlheinz Langanke +3

We have performed r-process calculations for matter ejected dynamically in neutron star mergers based on a complete set of trajectories from a three-dimensional relativistic smooth…

Neutrino-driven winds from neutron star merger remnants

Albino Perego, Stephan Rosswog, Ruben Cabezon +4

We present a detailed, 3D hydrodynamics study of the neutrino-driven winds that emerge from the remnant of a NS merger. Our simulations are performed with the Newtonian, Eulerian c…

MODA: a new algorithm to compute optical depths in multi-dimensional hydrodynamic simulations

A. Perego, E. Gafton, R. Cabezon +2

We introduce a new algorithm for the calculation of multidimensional optical depths in approximate radiative transport schemes, equally applicable to neutrinos and photons. Motivat…

EMMI Rapid Reaction Task Force Meeting on 'Quark Matter in Compact Star'

Michael Buballa, Veronica Dexheimer, Alessandro Drago +8

The recent measurement of two solar mass pulsars has initiated an intense discussion on its impact on our understanding of the high-density matter in the cores of neutron stars. A…

Astrophysical weak-interaction rates for selected and nuclei

G. Martínez-Pinedo, Y. H. Lam, K. Langanke +2

We have evaluated the electron capture rates on Ne, F, Mg, Na and the decay rates for F and Na at temperature and density conditions r…
