We report precise Doppler measurements of GJ849 (M3.5V) that reveal thepresence of a planet with a minimum mass of 0.82 Mjup in a 5.16 year orbit. Ata = 2.35 AU, GJ849b is the first Doppler-detected planet discovered around an Mdwarf to orbit beyond 0.21 AU, and is only the second Jupiter mass planetdiscovered around a star less massive than 0.5 Msun. This detection brings to 4the number of M stars known to harbor planets. Based on the results of oursurvey of 1300 FGKM main--sequence stars we find that giant planets within 2.5AU are ~3 times more common around GK stars than around M stars. Due to theGJ849's proximity of 8.8 pc, the planet's angular separation is 0."27, makingthis system a prime target for high--resolution imaging using adaptive opticsand future space--borne missions such as the Space Interferometry Mission. Wealso find evidence of a linear trend in the velocity time series, which may beindicative of an additional planetary companion.Comment: 12 pages, 3 figues, 2 tables, PASP Accepte
