Magnetic fields in single late-type giants in the Solar vicinity: How common is magnetic activity on the giant branches?
R. Konstantinova-Antova, M. Aurière, C. Charbonnel +6
We present our first results on a new sample containing all single G,K and M giants down to V = 4 mag in the Solar vicinity, suitable for spectropolarimetric (Stokes V) observation…
Magnetic Field Structure and Activity of the He-burning Giant 37 Comae
S. Tsvetkova, P. Petit, R. Konstantinova-Antova +4
We present the first magnetic map of the late-type giant 37 Com. The Least Squares Deconvolution (LSD) method and Zeeman Doppler Imaging (ZDI) inversion technique were applied. The…
BG Gem - a Poorly-Studied Binary with a Possible Black Hole Component
N. A. Drake, A. S. Miroshnichenko, S. Danford +1
BG Gem is an eclipsing binary with a 91.6-day orbital period. The more massive primary component does not seem to show absorption lines in the spectrum, while the less massive seco…
Multi-element Doppler imaging of the CP2 star HD 3980
N. Nesvacil, T. Lüftinger, D. Shulyak +8
In atmospheres of magnetic main-sequence stars, the diffusion of chemical elements leads to a number of observed anomalies, such as abundance spots across the stellar surface. The…
