Models for the 3 hour profile modulations. Hutchings, J. B. ; Bernard, J. E. ; Margetish, L. Abstract The amplitudes and time lags of the 3-hour periodic profile modulation are measured through several emission lines in spectrograms of V1500 Cygni taken in September 1975. A grid of predicted values of these quantities is calculated for possible models and compared with the observational data. These and considerations of the profile shape support and further define a previously proposed model. It is characterized by an equatorial ring, polar blobs, a 3.3-hour periodic searchlight illumination, an expansion velocity of about 2000 km/s, an inclination of approximately 50 deg, and time of outburst August 29.5 + or - 1 day.
