中文摘要 | EC19314-5915 is an eclipsing nova-like variable star with an orbital period of 4.75 h. The intensive high-speed photometry was obtained in 1992 June and July. In addition to the flickering activity, its mean light curve shows a quasi-periodic oscillation with a period of 582 s. To analyze the eclipses, a programme was written to synthesize the light curves. A model with an optically thick steady-state disc was adopted to reconstruct the light curves. No satisfactory solutions were obtained in the calculations. Future high-speed photometry and time-resolved spectroscopy are required for future study. |
