The origins of the magnetic field in tip-RGB, AGB and post-AGB stars
Renada Konstantinova-Antova, Stefan Georgiev, Agnès Lèbre +3
During the last decade and a half, the new generation spectropolarimeter Narval at Pic du Midi, France allowed the study of weak magnetic fields in cool giant stars that are fairly…
A long-term study of the magnetic field and activity in the M giant RZ Ari
R. Konstantinova-Antova, S. Georgiev, A. Lèbre +12
We present a detailed long-term study of the single M6 III giant RZ~Ari to obtain direct and simultaneous measurements of the magnetic field, activity indicators, and radial veloci…
The evolution of surface magnetic fields in young solar-type stars II: The early main sequence (250-650 Myr)
C. P. Folsom, J. Bouvier, P. Petit +6
There is a large change in surface rotation rates of sun-like stars on the pre-main sequence and early main sequence. Since these stars have dynamo driven magnetic fields, this imp…
The magnetic strip(s) in the advanced phases of stellar evolution - Theoretical convective turnover timescale and Rossby number for low- and intermediate-mass stars up to the AGB at various metallicities
C. Charbonnel, T. Decressin, N. Lagarde +7
Recent spectropolarimetric observations of otherwise ordinary G, K, and M giants revealed localized magnetic strips in the HRD coincident with the regions where the first dredge-up…
