Stratification and Isotope Separation in CP Stars
C. R. Cowley, S. Hubrig, F. G. Gonzalez
We investigate the elemental and isotopic stratification in the atmospheres of selected chemically peculiar (CP) stars of the upper main sequence. Reconfiguration of the UVES spect…
Spectropolarimetric Variability and Co-Rotating Structure in HD 92207
R Ignace, S Hubrig, M Scholler
We report on low resolution (R~3000) spectropolarimetry of the A0 supergiant star HD 92207. This star is well-known for significant spectral variability. The source was observed on…
Chemically peculiar stars and their temperature calibration
M. Netopil, E. Paunzen, H. M. Maitzen +2
The determination of effective temperature for chemically peculiar (CP) stars by means of photometry is a sophisticated task due to their abnormal colours. Standard calibrations fo…
Detection of variable Si II, Mn II and Fe II emission lines in the magnetic Bp star a Centauri
S. Hubrig, J. F. Gonzalez
The nature of non-variable high-excitation emission lines detected in the optical spectra of normal late-B type and chemically peculiar HgMn and PGa stars is still poorly understoo…
HD 65949: The Highest Known Mercury Excess Of Any CP Star?
Charles R. Cowley, S. Hubrig, G. F. Gonzalez +1
ESO spectra of HD 65949 show it to be unlike any of the well-known types within its temperature range 13600K. It is neither a silicon, nor a mercury-manganese star, thoug…
