Direct Evidence for an Enhancement of Helium in Giant Stars in Omega Centauri

A. K. Dupree, Jay Strader, Graeme H. Smith

The double main sequence identified in the globular cluster Omega Centauri has been interpreted using isochrones to indicate a large variation in the abundance of helium. If true,…

Thermohaline Mixing and its Role in the Evolution of Carbon and Nitrogen Abundances in Globular Cluster Red Giants: The Test Case of Messier 3

George C. Angelou, Ross P. Church, Richard J. Stancliffe +2

We review the observational evidence for extra mixing in stars on the red giant branch (RGB) and discuss why thermohaline mixing is a strong candidate mechanism. We recall the simp…

Evolution of massive stars with pulsation-driven superwinds during the RSG phase

Sung-Chul Yoon, Matteo Cantiello

Pulsations driven by partial ionization of hydrogen in the envelope are often considered important for driving winds from red supergiants (RSGs). In particular, it has been suggest…

Gyroscopic pumping of large-scale flows in stellar interiors, and application to Lithium Dip stars

Pascale Garaud, Peter Bodenheimer

The maintenance of large-scale differential rotation in stellar convective regions by rotationally influenced convective stresses also drives large-scale meridional flows by angula…

Direct Confirmation of the Asymmetry of the Cas A Supernova with Light Echoes

A. Rest, R. J. Foley, B. Sinnott +21

We report the first detection of asymmetry in a supernova (SN) photosphere based on SN light echo (LE) spectra of Cas A from the different perspectives of dust concentrations on it…
