Lithium evolution from Pre-Main Sequence to the Spite plateau: An environmental solution to the cosmological lithium problem

The Big Bang nucleosynthesis  predicts about three times as much lithium than that remains today in the old main sequence stars. This is the long-standing "cosmological lithium problem". Several fields of study, including non-standard cosmology models, yet unknown aspects of particle physics, nuclear physics, and stellar physics, have been pursued to provide possible explanations to the lithium deficit. My stellar model, by considering the stellar Li evolution from the pre-main sequence to the end of the main sequence phase, provides a new solution: the lithium was first destroyed and re-accumulated by these stars shortly after they were born. This environmental Li evolution model also offers the possibility to interpret the decrease of Li abundance in extremely metal-poor stars, the Li disparities in spectroscopic binaries and the low Li abundance in planet hosting stars.
