TT Hydrae (HD 97528) is an Algol-type interacting binary star system composed of a B9.5 V primary star and a K0 III-IV companion in a 6.95 day orbit. The companion fills its Roche Lobe and material is streaming into an accretion cloud around the primary. Ultraviolet spectra from FUSE, IUE, HST-FOS, and HST-GHRS taken over about twenty years are being analyzed to create a model of the gas flow in the system. The spectra are composed of ten emission spectra taken during totality of primary eclipse and eighteen absorption spectra from outside of primary eclipse totality.
