| Abstract: |
The low mass of M stars, less than 0.5 solar masses, combined with close in orbits yield radial velocity amplitudes for planets in the habitable zone around these stars that are well within current limits of 1-2 m/s achieved with visible-light instruments. These same instruments become significantly challenged when looking at M5 dwarfs and cooler. However, if one takes advantage of the fact that M-stars emit most of their energy in the near-infrared (NIR), hundreds of targets become accessible to 8-meter class telescopes with instruments such as the Precision Radial Velocity Spectrometer (PRVS) for Gemini. We present some preliminary laboratory results that demonstrate the viability and challenges of PRV work in the NIR. |
