Abstract

Context. The discovery of the Spite plateau in the abundances of for metal-poor stars led to the determination of an observationally deduced primordial lithium abundance. However, after the success of the Wilkinson Microwave Anisotropy Probe (WMAP) in determining the baryon density, , there was a discrepancy between observationally determined and theoretically determined abundances in the case of . One of the most important uncertain factors in the calculation of the stellar abundance is the effective temperature, .
