A key limitation of the gravitational lensing method ology is that it only produces a two-dimensional map of �, and hence raises the possibility that structures seen in the map are caused by physically unrelated masses along the line-of-sight. Because the background galaxies reside at a mean z � 1, ...

From the formula above, it is immediately clear that a contraction of the star under its own gravity will further raise the central temperature. Fusion in heavy stars will continue to keep the star alive as long as the reactions ar ...

P-nuclei
p-Nuclei (p stands for proton-rich) are certain proton-rich, naturally occurring isotopes of some elements between selenium and mercury which cannot be produced in either s- or r-process.
