The double polarization (beam-recoil) observables O-x and Oz have been measured for the reaction γ p → K+Λ from threshold production to Eγ ∼ 1500 MeV. The data were obtained with the linearly polarized beam of the GRAAL facility. Values for the target asymmetry T could also be extracted despite the use of an unpolarized target. Analyses of our results by two isobar models tend to confirm the necessity to include new or poorly known resonances in the 1900MeV mass region. © 2009 SIF, Springer-Verlag Berlin Heidelberg.
