Abstract
New spectroscopic observations of the B-type eclipsing binary IZ Persei are analysed via cross-correlation and disentangling codes to determine orbital parameters and separated spectra of the two stars for the first time. These results are combined with analysis of photometric data from the Hipparcos satellite and new ground-based CCD photometry to yield the first determination of complete astrophysical parameters for both stars in this semi-detached system that is in the slow phase of Case-A mass transfer.
