A search for strongly Mg-enhanced stars from the Sloan Digital Sky Survey

Strongly Mg-enhanced stars with [Mg/Fe] > 1.0 show peculiar abundance patterns and hence are of great interest for our understanding of stellar formation and chemical evolution of the Galaxy. A systematic search for strongly Mg-enhanced stars based on low-resolution (R ≃ 2000) spectra from the Sloan Digital Sky Survey (SDSS) …
