This paper reports a measurement of D*± meson production in jets from proton-proton collisions at a center-of-mass energy of √s = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |η|<2.5. D*± mesons found in jets are fully reconstructed in the decay chain: D*+ → D0π+, D0 →K-π+, and its charge conjugate. The production rate is found to be N(D*±)/N(jet) = 0.025 ± 0.001(stat.) ± 0.004(syst.) for D*± mesons that carry a fraction z of the jet momentum in the range 0.3<z<1. Monte Carlo predictions fail to describe the data at small values of z, and this is most marked at low jet transverse momentum.
