  We present here in full details the linear secular theory with tidal damping
that was used to constraint the fit of the HD10180 planetary system in (Lovis
et al. 2011). The theory is very general and can provide some intuitive
understanding of the final state of a planetary system when one or more planets
are close to their central star. We globally recover the results of (Mardling
2007), but we show that in the HD209458 planetary system, the consideration of
the tides raised by the central star on the planet lead to believe that the
eccentricity of HD209458b is most probably much smaller than 0.01.
