Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of

Impact of Uncertainties in Astrophysical Reaction Rates on Nucleosynthesis in the $\nu p$ Process

Autor: Rauscher, T., Nishimura, N., Cescutti, G., Hirschi, R., Murphy, A. St. J., Fröhlich, C.

Publikováno v: JPS Conf. Proc. 31 (2020) 011026

The $\nu p$ process appears in proton-rich, hot matter which is expanding in a neutrino wind and may be realised in explosive environments such as core-collapse supernovae or in outflows from accretion disks. The impact of uncertainties in nuclear re

Using isochronous mass spectrometry at the experimental storage ring CSRe in Lanzhou, the masses of $^{82}$Zr and $^{84}$Nb were measured for the first time with an uncertainty of $\sim 10$ keV, and the masses of $^{79}$Y, $^{81}$Zr, and $^{83}$Nb we

Pushing 1D CCSNe to explosions: model and SN 1987A

Autor: Perego, A., Hempel, M., Fröhlich, C., Ebinger, K., Eichler, M., Casanova, J., Liebendoerfer, M., Thielemann, F. -K.

Publikováno v: Astrophys. J. 806, 275 (2015)

We report on a method, PUSH, for triggering core-collapse supernova explosions of massive stars in spherical symmetry. We explore basic explosion properties and calibrate PUSH such that the observables of SN1987A are reproduced. Our simulations are b

Proton-rich nucleosynthesis and nuclear physics

Autor: Rauscher, T., Fröhlich, C.

Publikováno v: AIP Conf. Proc. 1484 (2012) 73

Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on the nu-p- and the gamma-proc
