Entropy, neutrino physics, and the lithium problem: Why are there stars with essentially no lithium due to serious lithium deficiency in certain spatial regions in the early universe?

摘要

The consequence of abnormally low lithium abundance in a nearby population II star (which is almost as old as the supposed population III stars) as represented by HE0107-5240 is that the standard BBN theory is out of sync with observations. The analysis of the big bang nucleosynthesis may help explain the anomalously low value of lithium abundance in the star HE0107-5240, which by orthodox BBN, should not exist, as explained by Shigeyama et al. (2003) [1].
