“…This seems to confirm all earlier and recent attempts which also were not able to obtain a satisfactory overall reproduction of the SS abundances in the region of the light trans-Fe p-nuclei the one or other way (see, e.g. Hoffman et al 1996Hoffman et al , 1997Meyer et al 2000;Rauscher et al 2002;Bazin et al 2008;Pignatari et al 2008;Fisker, Hoffman & Pruet 2009;Wanajo et al 2009). Therefore, two further refinements of our model may be necessary to improve the situation obtained so far: 1) a finer grid of individual values of Y e in the range 0.450 ≤ Y e ≤ 0.490, and/or 2) a superposition of Y e values with model-inherent weighting of the respective HEW yields.…”

Abstract:We have performed large-scale nucleosynthesis calculations within the high-entropy-wind (HEW) scenario of Type II supernovae. The primary aim was to constrain the conditions for the production of the classical 'p-only' isotopes of the light trans-Fe elements. We find, however, that for electron fractions in the range 0.458 ≤ Y e ≤ 0.478, sizeable abundances of p-, s-and r-process nuclei between 64 Zn and 98 Ru are coproduced in the HEW at low entropies (S ≤ 100) by a primary charged-particle process after an α-rich freezeout. With the above Y e -S correlation, most of the predicted isotopic abundance ratios within a given element, e.g. 64 Mo, Mo up to 'r-only' 100 Mo. Furthermore, our model is able to reproduce the isotopic composition of Mo in presolar SiC X-grains.

En périphérie de l’Iran, des espaces comme le Kurdistan d’Irak - tout comme Dubaï dont le cas est plus connu - profitent de la politique protectionniste de la république islamique et du différentiel transfrontalier pour mettre en place un commerce illégal important. La richesse alors créée a généré toute une réorganisation de l’espace frontalier. Elle a engendré aussi un ensemble de chaînes d’acteurs parfois fort complexe où intérêts économiques et politiques demeurent bien souvent entremêlés.
