Exploring the magnetic topologies of cool stars
J. Morin, J. -F. Donati, P. Petit +19
Magnetic fields of cool stars can be directly investigated through the study of the Zeeman effect on photospheric spectral lines using several approaches. With spectroscopic measur…
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…
Large-scale magnetic topologies of early M dwarfs
JF Donati, J Morin, P Petit +12
We present here additional results of a spectropolarimetric survey of a small sample of stars ranging from spectral type M0 to M8 aimed at investigating observationally how dynamo…
Large-scale magnetic topologies of mid-M dwarfs
J. Morin, J. -F. Donati, P. Petit +13
We present in this paper the first results of a spectropolarimetric analysis of a small sample (~ 20) of active stars ranging from spectral type M0 to M8, which are either fully-co…
