Abstract:
We have made a detailed spectral analysis of 11 Wide Angle Search for
Planets (WASP) planet host stars using high signal-to-noise ratio
(S/N) HARPS spectra. Our line list was carefully selected from the
spectra of the Sun and Procyon, and we made a critical evaluation of
the atomic data. The spectral lines were measured using equivalent
widths. The procedures were tested on the Sun and Procyon prior to be
being used on the WASP stars. The effective temperature (Teff),
surface gravity (logg), microturbulent velocity (vmic) and
metallicity were determined for all the stars.
Description:
The spectral synthesis package used was UCLSYN (University College
London SYNthesis). ATLAS9 models atmospheres without convective
overshooting are used and local thermodynamic equilibrium (LTE) is
assumed.
