HARPS-N is a high-precision spectrograph, similar to HARPS on the 3.6-m ESO telescope in Chile. It will be located in the Northern hemisphere on the INAF’s Telescopio Nazionale Galileo. The immediate scientific goal of HARPS-N is the observation of the Kepler transiting-planet candidates for the characterization and discovery of terrestrial planets by combining transits and Doppler measurements.


INAF Telescopio Nazionale Galileo has the responsibility of part of the control software. Furthermore it will prepare the  instrument location and will participate to the system integration and verification. It will participate to the commissioning of the instrument, its maintenance and operations.

INAF will contribute to the Scientific program with three co-Is that wil be part of the Science team in charge of the GTO program. The INAF community will have access to the instrument through the TNG open time usually available to the national community.

During the negotiation phase for the HARPS-N Consortium the Italian scientific community has started a discussion to organize itself for the best usage of the instrument and in particular has delivered a Science Document  collecting several ideas to capitalize the opportunity offered by HARPS-N to the national community. More than 40 researchers have contributed to this document including groups at several INAF Institutes (OOAA Arcetri, Bologna, Brera, Capodimonte, Catania, Padova, Palermo, Roma, Teramo, Torino e Trieste) and Universities (Padova, Catania).  The most significant contributions are devoted to the extrasolar planets astrophysics and include among the others:

  1. BulletKepler extrasolar science;

  2. Bulletsinergy with other ground and space based projects (GAIA, SPHERE, EPICS, PLATO);

  3. Bulletplanet search around low mass stars;

  4. Bulletinteraction between stellar activity and planets;

  5. Bulletplanets in special environment.

This document does not deal exhaustively with the possible usage of  HARPS-N by the Italian astrophysics community but indicates the large interest of the community and gives a solid starting point for an effective usage of the instrument.
