GALAH emission-line stars
We present a neural network autoencoder structure that is able to extract essential latent spectral features from observed spectra and then reconstruct a spectrum from those... -
Optical spectroscopy of classical Be stars
In this study, we analyse the emission lines of different species present in 118 Galactic field classical Be stars in the wavelength range of 3800-9000{AA}. We re-estimated the... -
H{alpha} spectra & V-band photometry of {delta} Sco
We model the circumstellar disk of {delta} Sco using the three-dimensional Monte Carlo radiative transfer code HDUST in order to quantify the large-scale changes in the disk... -
High-resolution spectra of * bet CMi
The late-type Be star {beta} CMi is remarkably stable compared to other Be stars that have been studied. This has led to a realistic model of the outflowing Be disk by Klement+... -
Radial velocities of {delta} Sco
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... -
Be stars in the exofield of CoRoT. III.
The search and interpretation of non-radial pulsations from Be star light curves observed with the CoRoT satellite requires to obtain high quality stellar astrophysical... -
Be star rotational velocities distribution
Among intermediate-mass and massive stars, Be stars are the fastest rotators in the main sequence (MS) and, as such, these stars are a cornerstone to validate models of... -
H{alpha} spectra of {pi} Aqr
The work is aimed at studying the circumstellar disk of the bright classical binary Be star pi Aqr. We analysed variations of a double-peaked profile of the Halpha emission line... -
Fundamental parameters of Be stars
In preparation for the COROT space mission, we determined the fundamental parameters (spectral type, temperature, gravity, vsini) of the Be stars observable by COROT in its... -
BV(RI)_C_H{alpha} photometry of NGC 663
We present new BV(RI)C_H{alpha} photometry of the young open cluster NGC 663. The H{alpha} photometry is complete down to magnitude R_C=15.4, corresponding to spectral type A5... -
Magnetic properties of {omega} Ori
One hundred and twenty-five new high-precision spectropolarimetric observations have been obtained with ESPaDOnS (Eschelle Spectro-Polarimetric Device for the Observation of... -
Interferometric observations of northern Be stars
We present the first K'-band, long-baseline interferometric observations of the northern Be stars {gamma} Cas, {phi} Per, {zeta} Tau, and {kappa} Dra. The measurements were made...
