    • Discovery of a complex linearly polarized spectrum of Betelgeuse dominated by depolarization of the continuum 
      Aurière, M.; López Ariste, A.; Mathias, P.; Lèbre, A.; Josselin, E.; Montargès, M.; Petit, P.; Chiavassa, A.; Paletou, F.; Fabas, N.; Konstantinova Antova, R.; Donati, J. F.; Grunhut, J. H.; Wade, W. A.; Herpin, F.; Kervella, Pierre; Perrin, G.; Tessore, B (EDP Sciences, 2016)
      Context. Betelgeuse is an M supergiant that harbors spots and giant granules at its surface and presents linear polarization of its continuum. Aims. We have previously discovered linear polarization signatures associated ...
    • Investigating the magnetospheric accretion process in the young pre-transitional disk system DoAr 44 (V2062 ... 
      Bouvier, J.; Alecian, E.; Alencar, S. H. P.; Sousa, A.; Donati, J. F.; Perraut, K.; Bayo, A.; Rebull, L. M.; Dougados, C.; Duvert, G.; Berger, J. P.; Benisty, M.; Pouilly, K.; Folsom, C.; Moutou, C. (EDP, 2020)
      Context. Young stars interact with their accretion disk through their strong magnetosphere.Aims. We aim to investigate the magnetospheric accretion/ejection process in the young stellar system DoAr 44 (V2062 Oph).Methods. ...
