We report the measurement of charged $D^*$ mesons in inclusive jets producedin proton-proton collisions at a center of mass energy $\sqrt{s}$ = 200 GeVwith the STAR experiment at RHIC. For $D^{*}$ mesons with fractional momenta$0.2 < z < 0.5$ in inclusive jets with 11.5 GeV mean transverse energy, theproduction rate is found to be $N(D^{*+}+D^{*-})/N(\mathrm{jet}) = 0.015 \pm0.008 (\mathrm{stat}) \pm 0.007 (\mathrm{sys})$. This rate is consistent withperturbative QCD evaluation of gluon splitting into a pair of charm quarks andsubsequent hadronization.
