Cool Stars 14 - Submitted Abstract # 258 This version created on 05 October 2006 Metallicity determination of M dwarfs with TripleSpec Barbara Rojas, Cornell University James Lloyd, Cornell University Travis Barman, University of California Los Angeles Host star metallicity is a determining factor in the abundance of planets. Above solar metallicity, the number of stars with planets increases and it appears to be a correlation between high stellar metallicity and the presence of multiple-planet systems. Doppler planet search surveys are starting to be undertaken in the near infrared, such as T-EDI, CRIRES, NAHUAL and Gemini PRVS, for planets around cool stars. We are investigating metallicity determination of M dwarfs with TripleSpec, a new large bandwith moderate resolution infrared spectrograph for 5-10 Meter telescopes, for preparatory science for M dwarf Radial Velocity surveys. ----------------------------------
