Orbital parameters of the bright binary alpha Draconis based on amateur spectra from the STAROS database
G. Bertrand, C. Buil, M. Le Lain +20
We present the results of a STAROS monitoring campaign on the bright eclipsing binary star alpha Draconis. Over 200 high-resolution spectra were obtained by an international group…
The birth of Be star disks I. From localized ejection to circularization
J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35
Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…
Outbursts and stellar properties of the classical Be star HD 6226
Noel D. Richardson, Olivier Thizy, Jon E. Bjorkman +58
The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disk. We analyze 659…
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…
