      Nazé, Yaël; Barbá, Rodolfo H.; Bagnulo, Stefano; Morrell, Nidia I.; Gamen, Roberto C.; Petit, Véronique; Neiner, Coralie (2016-12)
      Context. The detection of bright, hard, and variable X-ray emission in Tr16-22 prompted spectropolarimetric observations of this star, which in turn led to the discovery of a surface magnetic field. Aims. We want ...
    • Studying the photometric and spectroscopic variability of the magnetic hot supergiant ζ Orionis Aa 

      Buysschaert, Bram; Neiner, Coralie; Richardson, Noel D.; Ramiaramanantsoa, Tahina; David-Uraz, Alexandre; Pablo, Herbert; Oksala, Mary E.; Moffat, Anthony F.J.; Mennickent, Ronald E.; Legeza, S. (2017-06)
      Massive stars play a significant role in the chemical and dynamical evolution of galaxies. However, much of their variability, particularly during their evolved supergiant stage, is poorly understood. To understand the ...
