An empirical recipe for inelastic hydrogen-atom collisions in non-LTE calculations
Rana Ezzeddine, Thibault Merle, Bertrand Plez +3
We investigate the role of hydrogen collisions in NLTE spectral line synthesis, and introduce a new general empirical recipe to determine inelastic charge transfer (CT) and bound-b…
The mass-ratio and eccentricity distributions of barium and S stars, and red giants in open clusters
Mathieu Van der Swaelmen, Henri M. J. Boffin, Alain Jorissen +1
In order to identify diagnostics distinguishing between pre- and post-mass-transfer systems, the mass-ratio distribution and period - eccentricity (P - e) diagram of barium and S s…
Sodium abundances of AGB and RGB stars in galactic globular clusters I. Analysis and results of NGC 2808
Y. Wang, F. Primas, C. Charbonnel +4
Galactic globular clusters (GC) are known to have multiple stellar populations and be characterised by similar chemical features, e.g. O-Na anti-correlation. While second-populatio…
