Mirror principle and the red-giant bump: the battle of entropy in low-mass stars
S. Hekker, G. C. Angelou, Y. Elsworth +1
The evolution of low-mass stars into red giants is still poorly understood. During this evolution the core of the star contracts and, simultaneously, the envelope expands -- a proc…
On the Numerical Treatment and Dependence of Thermohaline Mixing in Red Giants
John Lattanzio, Lionel Siess, Ross Church +5
In recent years much interest has been shown in the process of thermohaline mixing in red giants. In low and intermediate mass stars this mechanism first activates at the position…
Lithium abundances in globular cluster giants: NGC 6218 (M12) and NGC 5904 (M5)
Valentina D'Orazi, George C. Angelou, Raffaele G. Gratton +5
Convergent lines of evidence suggest that globular clusters host multiple stellar populations. It appears that they experience at least two episodes of star formation whereby a fra…
Observational Constraints for Thermohaline Mixing
G. C. Angelou, J. C. Lattanzio, R. P. Church +1
We provide a brief review of thermohaline physics and why it is a candidate extra mixing mechanism during the red giant branch (RGB). We discuss how thermohaline mixing (also calle…
The case of the disappearing CN-strong AGB stars in Galactic globular clusters -- Preliminary Results
S. W. Campbell, D. Yong, E. C. Wylie-de Boer +5
A previously reported literature search suggested that the AGB stars in Galactic globular clusters may be showing different distributions of CN-strong and CN-weak stars as compared…
