Data pubblicazione: | 2016 | Titolo del volume in cui è pubblicato il poster: | Ground-based and Airborne Instrumentation for Astronomy VI | Curatore/i del volume in cui è pubblicato il contributo: | Evans, Christopher J.; Simard, Luc; Takami, Hideki | Serie: | PROCEEDINGS OF SPIE | Numero: | 9908 | Da pagina:: | 99086C | Abstract: | 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 and 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. | Titolo del convegno: | Ground-based and Airborne Instrumentation for Astronomy VI | Luogo del convegno: | Edinburgh, United Kingdom | Periodo del convegno: | 26 June - 1 July 2016 | URI: | http://hdl.handle.net/20.500.12386/26570 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9908/1/GIANO-and-HARPS-N-together--towards-an-Earth-mass/10.1117/12.2231898.full | ISSN: | 0277-786X | ISBN: | 9781510601963 9781510601956 |
