Title: H-alpha emission in M15 giants
Abstract: Three giant stars on the blue side of the red giant branch in M15 show emission in the wings of H-alpha. Monitoring the strength of this emission over decades may reveal characteristics of the stars upper atmospheres, providing clues to the source of the emission in these early AGB stars.
