Protostellar accretion in low mass metal poor stars and the cosmological lithium problem

Context.The cosmological lithium problem, that is, the discrepancy between the lithium abundance predicted by the Big Bang nucleosynthesis and the one observed for the stars of the "Spite plateau", is one of the long standing problems of modern astrophysics. Recent hints for a possible sol...
