HIGHLIGHTS

• who: Arnaboldi Magda and collaborators from the Karl-Schwarzschild-Str2, Garching, Germany Inter University Centre for and Astrophysics, Ganeshkhind, Post Bag, Pune, India have published the paper: The survey of planetary nebulae in Andromeda (M31) - V. Chemical enrichment of the thin and thicker discs of Andromeda: Oxygen to argon abundance ratios for planetary nebulae and HII regions, in the Journal: (JOURNAL)
• what: The authors propose using the log(O/Ar) versus (12 + log(Ar/H)) distribution of PNe with different ages to constrain the star formation histories of the parent stellar populations in the thin . . .
