Spectroscopic analysis of RGB stars in nine open clusters
Saulo de Oliveira Cantanhêde, Alan Alves-Brito, Rodolfo Smiljanic +4
Stellar clusters are crucial tools for studying the age, spatial distribution, dynamics, kinematics, and chemical composition of different Galactic stellar populations. In this wor…
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…
The Magnetic Fields at the Surface of Active Single G-K Giants
M. Aurière, R. Konstantinova-Antova, C. Charbonnel +15
We investigate the magnetic field at the surface of 48 red giants selected as promising for detection of Stokes V Zeeman signatures in their spectral lines. We use the spectropolar…
Descendants of Magnetic and non-Magnetic A-type Stars
M. Auriere, F. Lignieres, R. Konstantinova-Antova +4
We have studied the magnetic field of about 50 active and non-active single G-K-type red giants by means of spectropolarimetry with Narval and ESPaDOnS. 30 giants have been signifi…
Magnetic field structure in single late-type giants: Beta Ceti in 2010 - 2012
S. Tsvetkova, P. Petit, M. Auriere +5
The data were obtained using two spectropolarimeters - Narval at the Bernard Lyot Telescope, Pic du Midi, France, and ESPaDOnS at CFHT, Hawaii. Thirty-eight circularly-polarized sp…
Direct detection of a magnetic field in the photosphere of the single M giant EK Boo: How common is magnetic activity among M giants?
R. Konstantinova-Antova, M. Auriere, C. Charbonnel +6
We study the fast rotating M5 giant EK Boo by means of spectropolarimetry to obtain direct and simultaneous measurements of both the magnetic field and activity indicators, in orde…
Discovery of a weak magnetic field in the photosphere of the single giant Pollux
M. Auriere, G. A. Wade, R. Konstantinova-Antova +11
Aims: We observe the nearby, weakly-active single giant, Pollux, in order to directly study and infer the nature of its magnetic field. Methods: We used the new generation spectrop…
