Measurement of the spectrum of excited baryons and their decay is an important part of the effort to understand the structure of the nucleon. Coupled-channel analyses of pion, eta, and kaon production reactions are capable of extracting more information on the excited baryon resonances than a partial-wave analysis of each of the reactions individually. These will result in improved quark model predictions of the large mass N* states, where wide resonances and insufficient data make it difficult to differentiate the states from the background. These analyses are also an important part of understanding the effective degrees of freedom of the nucleon and will provide a better understanding of QCD.In the past several years, extensive work has been done on measuring cross sections and polarization observables of the kaon production reactions on the proton. To complement these data, the CLAS g13 experiment at Jefferson Lab collected 50 billion events on deuterium using circularly and linearly polarized photon beams. Along with studying the kaon production reactions on the neutron, the excited kaon and excited hyperon channels are being studied as well.It has been predicted that the s-channel production of the {gamma}n{yields}K*{sup 0}(892){Lambda} and {gamma}n{yields}K{sup +{Sigma}-}(1385) reactions will couple non-negligibly to the decays of several of the excited N* states. These include the N*(1495), N*(2070), and N*(2090) for K*{sup 0}(892){Lambda} production, and the N*(1980) and N*(2095) for K{sup +{Sigma}-}(1385) production [1]. With data from the CLAS g13 experiment, preliminary results from studies of the {gamma}D{yields}K*{sup 0}(892){Lambda}(p) and {gamma}D{yields}K{sup +{Sigma}-}(1385)(p) reactions will be shown.
