Continuous CCD photometry of Nova Aquilae 1995 was performed through the B, V, R and I filters during 3 nights in 1995 and through an I filter in 18 nights in 1996. Time-series analysis of the 1996 data reveals 2 periodicities in the light curve: 0.06005 +/− 0.00001 (which appears with its first harmonic) and 0.2558 +/− 0.0001 day, both with full amplitudes of about 0.015 mag. We cannot rule out that the 1-day aliases at 0.0639 and 0.2037 or 0.3438 day are the true periods. We suggest an intermediate-polar model as an interpretation for the two periods. The longer one is the orbital period of the binary system and the shorter one is the spin period of the hot magnetic white dwarf component. |
