Abstract: Electromagnetic form factors of D and D* mesons and Xi(cc), Sigma(c), Omega(c), and Omega(cc) baryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. Compared to the PDG values of the light-sector, i.e. pion and proton, charmed hadron results are systematically smaller.
