The Fine-structure Constant as a Probe of Chemical Evolution and AGB Nucleosynthesis in Damped Lyman-alpha Systems
Timothy P. Ashenfelter, Grant J. Mathews, Keith A. Olive
Evidence from a large sample of quasar absorption-line spectra in damped Lyman-alpha systems has suggested a possible time variation of the fine structure constant alpha. The most…

The Chemical Evolution of Mg Isotopes vs. the Time Variation of the Fine Structure Constant
T. Ashenfelter, Grant J. Mathews, Keith A. Olive
The many-multiplet method applied to high redshift quasar absorption spectra has indicated a possible time variation of the fine structure constant. Alternatively, a constant value…
