| Abstract: |
The extension of the highly successful Doppler technique into the near-infrared (0.9-2.5 μm) is opening new parameter domains for extra-solar planet searches in terms of ages and masses of the primary stars. Here we present the current status of NAHUAL, a next generation near-infrared spectrograph for the 10.4-meter Gran Telescopio Canarias (GTC). Among its observing modes, it includes a hyper-stable high-resolution capability aimed at high-precision Doppler measurements of cool stars in the near-infrared. The sticky question of the best wavelength calibration for the near-infared is addressed in the last section of this paper. |
