  NAHUAL, a high-resolution near-infrared echelle spectrograph for large
  telescopes (10.4 m GTC)

  The radial velocity method has been successfully applied to discover hundreds
  of exoplanets (including super-Earths  around sun-like stars. In the next
  years, this technique will be applied to search for exoplanets around early M
  dwarfs with precisions of a few meters per second in the near-infrared using
  intermediate size telescopes. With a 10-m class telescope and similar
  precisions it is possible to search for exoplanets around young stars, very
  low-mass stars and brown dwarfs, a niche that currently remains quite
  unexplored. I will discuss about key challenges to face and possible solutions
  to achieve such goal: how to rearrange the target's signal to feed the
  spectrograph, how to achieve a high instrument stability, cryogenic issues,
  etc.
