Vertical stratification of iron abundance in atmospheres of blue horizontal-branch stars
V. Khalack, F. LeBlanc, B. B. Behr +2
The observed slow rotation and abundance peculiarities of certain blue horizontal branch (BHB) stars suggests that atomic diffusion can be important in their stellar atmospheres an…
Scandium: A key element for understanding Am stars
F. LeBlanc, G. Alecian
{\rm Context.} Atomic diffusion is believed to cause the abundance anomalies observed in AmFm stars. However, the detailed process has still not been well-established. For instance…
Search for vertical stratification of metals in atmospheres of blue horizontal-branch stars
V. R. Khalack, F. LeBlanc, B. B. Behr +2
The observed abundance peculiarities of many chemical species relative to the expected cluster metallicity in blue horizontal-branch (BHB) stars presumably appear as a result of at…
Vertical abundance stratification in the blue horizontal branch star HD135485
V. R. Khalack, F. LeBlanc, D. Bohlender +2
It is commonly believed that the observed overabundances of many chemical species relative to the expected cluster metallicity in blue horizontal branch (BHB) stars appear as a res…
