alfa: a constant that is not a constant?

Abstract

We review the observational information on the constancy of the fine structure constant a . We find that small improvements on the measurement of 187 Re lifetime can provide significant progress in exploring the range of variability suggested by QSO data. We also discuss the effects of a time varying a on stellar structure and evolution. We find that radioactive dating of ancient stars can offer a new observational window. DOI: 10.1007/10857580_14
