Bayesian sampling with BeAtlas, a grid of synthetic Be star spectra I. Recovering the fundamental parameters of αEri and βCMi
A. C. Rubio, A. C. Carciofi, P. Ticiani +14
Classical Be stars are fast rotating, near main sequence B-type stars. The rotation and the presence of circumstellar discs profoundly modify the observables of active Be stars. Ou…
The binary system of the spinning-top Be star Achernar
P. Kervella, S. Borgniet, A. Domiciano de Souza +16
Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar win…
Dynamical masses of the primary Be star and the secondary sdB star in the single-lined binary kappa Dra (B6 IIIe)
R. Klement, D. Baade, Th. Rivinius +16
Because many classical Be stars may owe their nature to mass and angular-momentum transfer in a close binary, the present masses, temperatures, and radii of their components are of…
Multitechnique testing of the viscous decretion disk model I. The stable and tenuous disk of the late-type Be star CMi
R. Klement, A. C. Carciofi, T. Rivinius +10
The viscous decretion disk (VDD) model is able to explain most of the currently observable properties of the circumstellar disks of Be stars. However, more stringent tests, focusin…
Contamination by field late-M, L and T dwarfs in deep surveys
J. A. Caballero, A. J. Burgasser, R. Klement
Context: Deep photometric surveys for substellar objects in young clusters and for high-redshift quasars are affected by contaminant sources at different heliocentric distances.If…
Newborn Be star systems observed shortly after mass transfer
Th. Rivinius, R. Klement, S. D. Chojnowski +24
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been discovere…
