Pascal Petit,François Lignières,Gregg A. Wade,Michel Aurière,Torsten Böhm,Stefano Bagnulo,B. Dintrans,A. Fumel,Jason Grunhut,J. Lanoux,A. Morgenthaler,Valérie Van Grootel +11 more
TL;DR: In this article, the authors used a cross-correlation procedure to compute, from each spectrum, a mean polarized line profile with a signal-to-noise ratio of about 20 000.
Journal ArticleDOI

TL;DR: In this article, the authors investigated the long-term temporal evolution of the magnetic field of the solar-type star ξ Bootis A, both from direct magnetic field measurements and from the simultaneous estimate of indirect activity indicators.
Journal ArticleDOI
