Period -- mass-loss rate relation of Miras with and without technetium [PDF]

arXiv, 2014
We present the discovery that Mira variables separate in two distinct sequences in a near- to mid-IR color versus pulsation period diagram, if a distinction is made with respect to the presence of technetium (Tc) in the stars. Tc is an indicator of recent or ongoing deep mixing during a third dredge-up event.
