Rotation and lithium in single giant stars
J. R. De Medeiros, J. D. do Nascimento, S. Sankarankutty +2
In the present work, we study the link between rotation and lithium abundance in giant stars of luminosity class III, on the basis of a large sample of single stars of spectral typ…
Ca II activity and rotation in F-K evolved stars
L. Pasquini, J. R. de Medeiros, L. Girardi
(Abridged) Ca II H and K high resolution observations for 60 evolved stars in the field and in 5 open clusters are presented. From these spectra chromospheric fluxes are derived, a…
Lithium and rotation on the subgiant branch II. Theoretical analysis of observations
J. D. do Nascimento, C. Charbonnel, A. Lebre +2
Lithium abundances and rotation, determined for 120 subgiant stars in Lebre et al. (1999) are analyzed. To this purpose, the evolutionary status of the sample as well as the indivi…
