Chemical evolution of Mg isotopes versus the time variation of the fine structure constant

Chemical evolution of Mg isotopes versus the time variation of the fine structure constant

We show that the synthesis of (25,26)Mg at the base of the convective envelope in low-metallicity asymptotic giant branch stars can produce the isotopic ratios needed to explain the low-z subset (with z
