Accurate LTE abundances for some lambda Boo stars
S. M. Andrievsky, I. V. Chernyshova, V. G. Klochkova +1
High-resolution and high S/N CCD spectra were analyzed to determine accurate LTE abundances in four lambda Boo stars: pi^1 Ori, 29 Cyg, HR 8203 and 15 And. In general, 14 chemical…

The unusual A-star VW Ari: chemical composition revisited
I. V. Chernyshova, S. M. Andrievsky, V. V. Kovtyukh +1
Seven high-resolution and high S/N CCD spectra were used to derive elemental abundances in the atmosphere of VW Ari A (T_eff=7200, log g=3.7) which is the primary component of a vi…
