Abstract: The B-emission stars 48 Per (HD 25940, HR 1273) and ψ Per (HD 22192, HR 1087) share similar stellar parameters with their disks viewed near pole-on in the case of 48 Per, and near edge-on for ψ Per. An extensive set of high-quality interferometric observations were obtained for both stars between 2006 and 2011 with the Navy Precision Optical Interferometer (NPOI) in the Hα emitting region. Using a three-step modelling process, model visibilities are compared to observations with a view toward achieving better constraints on the disk models than were possible with previous studies.
