Astronomers have discovered a new post-asymptotic giant branch (PAGB) star in a Galactic globular cluster known as ESO 37-1 (or E3 for short) and derived its fundamental parameters. The finding is ...

This measurement has profound effects on the production of radioactive lead (²⁰⁵Pb) in asymptotic giant branch (AGB) stars and can be used to help determine the sun's formation time.

allowing carbon‐enhanced ejecta from intermediate‐mass asymptotic giant branch stars to enrich the interstellar medium while star formation was still occurring. We are grateful to the staff of Keck ...
