- Title: Accurate LTE abundances for some lambda Boo stars
- Keyword(s): STARS: LAMBDA BOO, STARS: CHEMICALLY PECULIAR
- Pages: 446 -- 448
High-resolution and high S/N CCD spectra were analyzed to determine
accurate LTE abundances in four lambda Boo stars: pi1 Ori, 29 Cyg,
HR 8203 and 15 And. In general, 14 chemical elements were investigated. The
main results are the following: all stars have a strong deficiency of the
majority of investigated metals. Oxygen exhibits a moderate deficiency.
The carbon abundance is close to the solar one. The results obtained support
an accretion/diffusion model, which is currently adopted for the
explanation of the lambda Boo phenomenon.
