We discuss the effects due to the rotational deformation and the optically-thin line force on
the confinement of one-armed oscillations in the inner part of Be-star discs. The period of …

This paper presents a detailed statistical determination of the equatorial rotation rates of
classical Be stars. The rapid rotation of Be stars is likely to be linked to the ejection of gas …

We present the results of statistical analyses of a sample of 627 Be stars. The parameters of
intrinsic polarization, projected rotational velocity, and near IR excesses have been …

We present an atlas of Hγ, He i λ 4471 and Mg ii λ 4481 line profiles obtained in a 10 year
observation period of 116 Be stars, which enabled many of them to be observed at quite …

We report on the Swift Burst Alert Telescope detection of a short burst from the direction of
the TeV binary LS I+ 61 303, resembling those generally labeled as magnetar-like. We show …

A correlation between the orbital period and the strength of the Hα line in Be/X-ray binaries
has been found. Those systems with shorter orbital periods show less emission in Hα than …

The observations of all known major activity phases of the disks around the classical Be
stars γ Cas and 59 Cyg with low-mass companions are comprehensively reviewed and …

Line formation in Be star circumstellar disks Shear broadening, shell absorption ADS
Classic is now deprecated. It will be completely retired in October 2019. This page will …

We present the first long-term study of the optical counterpart to the X-ray pulsar RX J0440.
9+ 4431/LS V+ 44 17. The data consist of optical spectroscopic and infrared photometric …

We report optical and infrared photometric and spectroscopic observations that identify the
counterpart to the 358.6-s X-ray transient pulsar SAX J2103. 5+ 4545 with a moderately …
