Astron. 52, 115 (2002) PROBING THE STRUCTURE A N D ATMOSPHERES OF EXTRA-SOLAR PLANETS N. C. pt In this paper we review the recent results concerning the detection of extra-solar planets, with particular emphasis on the cases where a transit event is measured. 1. I n t r o d u c t i o n From 1995 to the present, following the discovery of the first extra-solar planet orbiting a solar type star 1 6 , about 160 giant planets have been announced, showing t h a t these are common around stars in the solar neighborhood 3 '.

In this section we report the results of DAOSPEC in a big sample composed of 62 stars. 000, s/n ~ 200 - 400), on October 2004. The lines used to do this test are standard Fe I and Fe II lines used to determine stellar parameters. A list of this lines can be found in Santos et al. (2004). One of the parameters of DAOSPEC is the wavelength interval for the calculation. Using the full individual spectrum interval yielded a large dispersion of the measurements. This comes from the fitting of the continuum level and, therefore, we considered small intervals, 500A wide, instead.
