Space-time variation of the fine-structure constant and evolution of isotope abundances
No full textAt present several groups are analyzing astrophysical data in a search for the time variation of the fine-structure constant alpha. Here we discuss how to exclude systematic effects caused by changes in the isotope abundances during the evolution of the
