Globular clusters display significant variations in their light-element content, pointing to the existence of a second stellar generation formed from the ejecta of an earlier generation. The nature of these internal polluters is still a matter of deb... Read More about On the internal pollution mechanisms in the globular cluster NGC 6121(M4): Heavy-element abundances and AGB models.
