    • Eta Carinae's 2014.6 spectroscopic event: Clues to the long-term recovery from its Great Eruption 

      Mehner, A.; Davidson, K.; Humphreys, R. M.; Walter, F. M.; Baade, D.; Wit, W. J. de; Martin, J.; Ishibashi, K.; Rivinius, T.; Martayan, C.; Ruiz González, María Teresa; Weis, K. (ESO, 2015)
      Aims. Every 5.5 years, eta Car's light curve and spectrum change remarkably across all observed wavelength bands. These so-called spectroscopic events are most likely caused by the close approach of a companion. We compare ...
    • VLTI/PIONIER images the Achernar disk swell 

      Vedova, G. Dalla; Millour, F.; Souza, A. Domiciano de; Petrov, R. G.; Faes, D. Moser; Carciofi, A. C.; Kervella, Pierre; Rivinius, T. (EDP Sciences, 2017-05)
      Context. The mechanism of disk formation around fast-rotating Be stars is not well understood. In particular, it is not clear which mechanisms operate, in addition to fast rotation, to produce the observed variable ejection ...
