  The GAPS project is running since 2012 with the goal to optimize the science
return of the HARPS-N instrument mounted at Telescopio Nazionale Galileo. A
large number of astronomers is working together to allow the Italian community
to gain an international position adequate to the HARPS-N capabilities in the
exoplanetary researches. Relevant scientific results are being obtained on both
the main guidelines of the collaboration, i.e., the discovery surveys and the
characterization studies. The planetary system discovered around the southern
component of the binary XO-2 and its characterization together with that of the
system orbiting the northern component are a good example of the completeness
of the topics matched by the GAPS project. The dynamics of some planetary
systems are investigated by studying the Rossiter-McLaughlin effect, while host
stars are characterized by means of asteroseismology and star-planet
interaction.
