Spectral analysis and abundances of the post-HB star HD 76431
V. Khalack, B. Yameogo, F. LeBlanc +4
HD76431 is a slow rotating post-HB star that shows an underabundance of helium by 0.5 dex relative to the solar value. These observational facts suggest that atomic diffusion could…

New observations of chemically peculiar stars with ESPaDOnS
V. Khalack, B. Yameogo, C. Thibeault +1
We present the first results of the estimation of gravity and effective temperature for some poorly studied chemically peculiar stars that were recently observed with the spectropo…

Hot horizontal branch stars in NGC 288 - effects of diffusion and stratification on their atmospheric parameters
S. Moehler, S. Dreizler, F. LeBlanc +5
NGC288 is a globular cluster with a well-developed blue horizontal branch covering the u-jump that indicates the onset of diffusion. It is therefore well suited to study the effect…
