Magnetic field, rotation, and binarity of the first magnetic B[e] star, IRAS 17449+2320

I. Bermejo Lozano, G. A. Wade, C. P. Folsom +1

IRAS 17449+2320 is the first identified magnetic B[e] star. It belongs to a subgroup of peculiar hot B-type stars, called FS~CMa stars. presenting the B[e] phenomenon, i.e., permit…

A new look into the spectral and light variations of epsilon Aur

P. Harmanec, H. Božić, D. Korčáková +9

Investigating long series of spectral and photometric observations, we found that the orbital elements of epsilon Aur are subject to much larger uncertainties than usually believed…

Calcium Emission in Interacting Binary Be Stars

Pavel Koubský, Lenka Kotková, Viktor Votruba +7

Polidan (1976) suggested that Be stars showing the CaII IR triplet in emission are interacting binaries. With the advent of the Gaia satellite, which will host a spectrometer to ob…

Properties and nature of Be stars: 29. Orbital and long-term spectral variations of γ Cassiopeiæ

J. Nemravová, P. Harmanec, P. Koubský +6

A detailed analysis of more than 800 electronic high-resolution spectra of gamma Cas, which were obtained during a time interval of over 6000 days (16.84 yrs) at several observator…

Radiative transfer in moving media II. Solution of the radiative transfer equation in axial symmetry

D. Korčáková, J. Kubát

A new method for the formal solution of the 2D radiative transfer equation in axial symmetry in the presence of arbitrary velocity fields is presented. The combination of long and…
