Its host star is a M2.5 dwarf, has a mass of 0.45±0.05M, a radius of 0.43±0.03R and lies 19.8±0.6pc away from our Sun. The planet is detected after a radial-velocity campaign using the ESO/Harps spectrograph. GJ3634b had an a priori geometric probability to undergo transit of ∼7% and, if telluric in composition, a non-grazing transit would produce a photometric dip of ≲0.1%. We therefore followed-up upon the RV detection with photometric observations using the 4.5-um band of the IRAC imager onboard Spitzer. Our six-hour long light curve excludes that a transit occurs for 2sigma of the probable transit window, decreasing the probability that GJ3634b undergoes transit to ∼0.5%. Description: The tables contain radial-velocity and photometry time series of GJ3634. Radial velocities were obtained with he HARPS spectrograph on the 3.6m telescope at La Silla, Chile. Photometry was obtained with Spitzer.
