Abstract:
Detailed chemical abundances of volatile and refractory elements have
been discussed in the context of terrestrial-planet formation during
in past years.
The HARPS-GTO high-precision planet-search program has provided an
extensive database of stellar spectra, which we have inspected in
order to select the best-quality spectra available for late type
stars. We study the volatile-to-refractory abundance ratios to
investigate their possible relation with the low-mass planetary
formation.
Description:
We present a fully differential chemical abundance analysis using
high-quality HARPS and UVES spectra.
We have derived in a line-by-line basis the chemical abundances of F-,
G-type stars. We provide several tables with the abundance ratios,
[X/Fe], and their uncertainties, e_[X/Fe], of 24 elements of 29 stars
with planets and 32 stars without planets.

Note (1): When the abundance ratio of element X, [X/Fe], or its uncertainty
is equal to 99.99, this means that for this star there is no abundance
measurement of element X.
