We are currently carrying out a search for planets around the lowest-mass stars using the CRIRES instrument at the VLT under the auspices of an ESO Large Programme. The main purposes of this work are to illuminate the correlation between stellar mass and planet formation, improve the census of planets, and identify new planets that can be followed-up for detailed study. We have developed, and are utilizing a new type of gas cell for obtaining high-precision radial velocities of late-type stars in the nIR spectral region. Observations in the nIR offer the advantages in that the targeted stars are bright enough for high-precision spectroscopy, and that the noise contribution from stellar activity is significantly reduced. We will describe the new gas cell and our radial velocity measurement algorithm, and present extensive tests of the obtained precision.
