Evolution of the disk of pi Aqr: from near-disappearance to a strong maximum
Y. Naze, G. Rauw, J . Guarro Flo +30
Some Be stars display important variability of the strength of the emission lines formed in their disk. This is notably the case of pi Aqr. We present here the recent evolution of…
Doppler tomography of the circumstellar disk of π Aquarii
S. V. Zharikov, A. S. Miroshnichenko, E. Pollmann +17
The work is aimed at a study of the circumstellar disk of the bright classical binary Be star π Aqr. We analysed variations of a double-peaked profile of the Hα emission line in th…
The 2011 Periastron Passage of the Be Binary delta Scorpii
A. S. Miroshnichenko, A. V. Pasechnik, N. Manset +19
We describe the results of the world-wide observing campaign of the highly eccentric Be binary system delta Scorpii 2011 periastron passage which involved professional and amateur…
The relationship between gamma Cassiopeiae's X-ray emission and its circumstellar environment
M. A. Smith, R. Lopes de Oliveira, C. Motch +17
γCas is the prototypical classical Be star and is best known for its variable hard X-ray emission. To elucidate the reasons for this emission, we mounted a multiwavelength campaign…
Cyclic variability of the circumstellar disk of the Be star zetaTau - I. Long-term monitoring observations
S. Stefl, Th. Rivinius, A. C. Carciofi +9
Emission lines formed in decretion disks of Be stars often undergo long-term cyclic variations, especially in the violet-to-red (V/R) ratio of their primary components. From observ…
