The impact of (n,) reaction rate uncertainties on the predicted abundances of i-process elements with in the metal-poor star HD94028
John E. McKay, Pavel A. Denissenkov, Falk Herwig +2
Several anomalous elemental abundance ratios have been observed in the metal-poor star HD94028. We assume that its high [As/Ge] ratio is a product of a weak intermediate (i) neutro…

The impact of (n,) reaction rate uncertainties of unstable isotopes near on the i process nucleosynthesis in He-shell flash white dwarfs
Pavel Denissenkov, Georgios Perdikakis, Falk Herwig +6
The first peak s-process elements Rb, Sr, Y and Zr in the post-AGB star Sakurai's object (V4334 Sagittarii) have been proposed to be the result of i-process nucleosynthesis in a po…

The impact of (n,) reaction rate uncertainties of unstable isotopes on the i-process nucleosynthesis of the elements from Ba to W
Pavel A. Denissenkov, Falk Herwig, Georgios Perdikakis +1
The abundances of n-capture elements in the CEMP-r/s stars agree with predictions of intermediate n-density nucleosynthesis, at -$10^{15} \mathrm{cm}^{-3}…
