Fluorine and Sodium in C-rich low-metallicity stars
Sara Lucatello, Thomas Masseron, Jennifer A. Johnson +2
We present the N, O, F and Na abundance and 12C/13C isotopic ratio measurements or upper limits for a sample of 10 C-rich, metal-poor giant stars, eight enhanced in s-process (CEMP…
Are Proto-Planetary Nebulae Shaped by a Binary? Results of a Long-Term Radial Velocity Study
Bruce J. Hrivnak, Wenxian Lu, Katrina Loewe Wefel +4
The shaping of the nebula is currently one of the outstanding unsolved problems in planetary nebula (PN) research. Several mechanisms have been proposed, most of which require a bi…
On the alpha formalism for the common envelope interaction
Orsola De Marco, Jean-Claude Passy, Maxwell Moe +3
The α-formalism is a common way to parametrize the common envelope interaction between a giant star and a more compact companion. The α parameter describes the fraction of orbital…
Thermohaline Mixing: Does It Really Govern the Atmospheric Chemical Composition of Low-Mass Red Giants?
Pavel A. Denissenkov, William J. Merryfield
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previou…
The RAVE Survey: Rich in Very Metal-Poor Stars
Jon P. Fulbright, Rosemary F. G. Wyse, Gregory R. Ruchti +20
Very metal-poor stars are of obvious importance for many problems in chemical evolution, star formation, and galaxy evolution. Finding complete samples of such stars which are also…
Fiducial Stellar Population Sequences for the VJKs Photometric System
Crystal Brasseur, Peter B. Stetson, Don A. VandenBerg +3
We have obtained broad-band near-infrared photometry for seven Galactic star clusters (M92, M15, M13, M5, NGC1851, M71 and NGC6791) using the WIRCam wide-field imager on the Canada…
