Asteroseismic sensitivity to internal rotation along the red-giant branch
F. Ahlborn, E. P. Bellinger, S. Hekker +2
Transport of angular momentum in stellar interiors is currently not well understood. Asteroseismology can provide us with estimates of internal rotation of stars and thereby advanc…
The Aarhus red giants challenge II. Stellar oscillations in the red giant branch phase
J. Christensen-Dalsgaard, V. Silva Aguirre, S. Cassisi +23
Context. The large quantity of high-quality asteroseismic data that obtained from space-based photometric missions and the accuracy of the resulting frequencies motivate a careful…
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…
The Aarhus Red Giants Challenge I: Stellar structures in the red giant branch phase
V. Silva Aguirre, J. Christensen-Dalsgaard, S. Cassisi +23
(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
Cyanogen in NGC 1851 RGB and AGB Stars: Quadrimodal Distributions
S. W. Campbell, D. Yong, E. C. Wylie-de Boer +7
The Galactic globular cluster NGC 1851 has raised much interest since HST photometry revealed that it hosts a double subgiant branch. Here we report on our homogeneous study into t…
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…
