GIANO and HARPS-N together, towards an Earth-mass detection instrument

Tozzi, A.; Oliva, E.; Iuzzolino, M.; Fini, L.; Puglisi, A.; Sozzi, M.; Falcini, G.; Carbonaro, L.; Ghedina, A.; Mercatelli, L.; Seemann, U.; Claudi, R.

This article describes the works we are doing for modifying the interface between the high resolution infrared spectrograph GIANO (0.97-2.4 micron) and the TNG telescope, passing from a fiber feed configuration to the original design of a direct light-feeding from the telescope to the spectrograph. So doing the IR spectrograph, GIANO, will work in parallel to HARPS-N spectrometer (0.38-0.70 micron), the visible high resolution spectrograph, thanks to a new telescope interface based on a dichroic window that simultaneously feeds the two instrumentes: this is GIARPS (GIAno & haRPS). The scientific aims of this project are to improve the radial velocity accuracy achievable with GIANO, down to a goal of 1 m/s, the value necessary to detect Earth-mass planets on habitable orbits around late-M stars, to implement simultaneous observations with Harps-N and GIANO optimizing the study of planets around cool stars. The very broad wavelengths range is particularly important to discriminate false radial velocity signals caused by stellar activity. We therefore include several absorption cells with different mixtures of gases and a stabilized Fabry Perot cavity, necessary to have absorption lines over the 0.97-2.4 microns range covered by GIANO. The commissioning of GIARPS is scheduled by the end of 2016.

GIANO: an Ultra-Stable IR Echelle Spectrometer for the TNG Telescope

Oliva E., Origlia L., Maiolino R., Gennari S., Biliotti V., Rossetti E., Baffa C., Leone F., Montegriffo P., Lolli M., D'Amato F., Bruno P., Scuderi S., Ghinassi F., Gonzalez M., Lodi M., Falcini G., Giani E., Marcucci G., Sozzi M.

GIANO is an IR cross-dispersed echelle spectrometer designed to achieve high throughput, high resolving power, wide band coverage and high accuracy radial velocity measurements. It also includes polarimetric capabilities and a low resolution mode that make it a very versatile, common user instrument which will be permanently mounted and available at one of the Nasmyth foci of the Telescopio Nazionale Galileo (TNG) located at Roque de Los Muchachos Observatory (ORM), La Palma, Spain. This project was selected by INAF as the top priority instrument among those proposed within the Second Generation Instrumentation Plan of the TNG.
