    Notes: [Auszug] An ordinary type II supernova explosion ejects more than half its original mass, and so no pre-existing planets would survive in bound orbits. Nor could planets form after such an event: a small fraction of the inner envelope (M 1CT3 M0; ref. 2) could fall back towards the newborn neutron star, and ...

    Notes: [Auszug] When compared with the observed abundances of light elements, the standard theory of primordial nucleosynthesis (which assumes a perfectly homogeneous universe) places severe constraints on the fraction of the closure density of the Universe in the form of baryons1: 0.04 ^nbaryon^ 0.1. Here we ...
