The explosive carbon burning theory studied by Arnett predicts an overdeficiency of Al relative to Mg in metal-poor stars. Analyses of such stars by Peterson have shown a good agreement with Arnett's theory. But other measurements of Al abundance on six cool metal-poor stars have not shown any significant deficiency. The author has obtained high quality spectra (high resolution, good S/N ratio) in the region of the weak lines of aluminum at 6696 and 6698 Å for six metal-poor stars. The abundances of Al derived from these lines are very reliable; they do not show Al overdeficiency. According to Arnett's theory, the synthesis of light metals by carbon burning has not taken place in explosive conditions.
