Variability of the He i 5876 Å line in early type chemically peculiar stars
Chemically peculiar stars present spectral and photometric variability with a single period. In the oblique rotator model, the non homogeneous distribution of elements on the stellar surface is at the origin of the observed variations. As to helium weak stars, it has been suggested that photometric and helium line equivalent width variations are out of phase. To understand the behaviour of heli...
متن کاملHelium in Chemically Peculiar Stars
For the purpose of deriving the helium abundances in chemically peculiar stars, the importance of assuming a correct helium abundance has been investigated for determining the effective temperature and gravity of main sequence B-type stars, making full use of the present capability of reproducing their helium lines. Even if the flux distribution of main sequence B-type stars appears to depend o...
متن کاملMultiplicity of chemically peculiar stars
Recently, with the goal to study multiplicity of chemically peculiar stars, we carried out a survey of 40 stars using diffraction limited near infrared (IR) imaging with NAOS-CONICA (NACO) at the VLT. Here, we announce the detection of 27 near IR companion candidates around 25 late B-type chemically peculiar stars exhibiting strong overabundances of the chemical elements Hg and Mn in their atmo...
متن کاملMagnesium abundance in main sequence B-type and magnetic chemically peculiar stars
The abundance of magnesium for a sample of 19 main sequence B-type and 41 magnetic chemically peculiar stars has been derived by spectrum synthesis analysis of the Mgii 448.1 nm line under the LTE assumption. The logarithm of the average Mg abundance for the main sequence stars is log (N(Mgii)/N(Tot)) =−4.28±0.19. Comparing magnetic chemically peculiar (Cp) and main sequence stars with equal ef...
متن کاملMultiplicity among chemically peculiar stars II . Cool magnetic Ap stars ⋆
We present new orbits for sixteen Ap spectroscopic binaries, four of which might in fact be Am stars, and give their orbital elements. Rough estimates of the individual masses of the components of HD 65339 (53 Cam) are given, combining our radial velocities with the results of speckle interferometry and with Hipparcos parallaxes. Considering the mass functions of 74 spectroscopic binaries from ...
