Descripción
It is well known that stars with orbiting giant planets have a higher
metallic content than stars without detected planets. In addition, we
have found that solar-type stars with planets present an extra Li
depletion when compared with field stars. On the other hand, Be needs a
greater temperature to be destroyed, so we may find such a relation in
cooler stars, whose convective envelopes are deep enough to carry
material to layers where Be can be burned. We present Li and Be
abundances for an extensive sample of stars with and without detected
planets, covering a wide range of effective temperatures (4700-6500 K)
with the aim of studying possible differences between the abundances of
both groups. The processes that take place in the formation of planetary
systems may affect the mixing of material inside their host stars and
hence the abundances of light elements.
