D* (+jets) in Deep Inelastic Scattering and Photoproduction
  New results on charm quark production at HERA in an increased phase space in deep-inelastic scattering and photoproduction are discussed. Single & double-differential cross section distributions are compared to next-to-leading order QCD calculations as well as to MC@NLO in the photoproduction regime. The charm contribution to the proton structure, F_2^cc(x,Q^2), is determined with different experimental techniques and finally combined.
