The Photometric Period of V1974 Cygni (Nova Cygni 1992)

We present the discovery of the photometric (orbital) period for V1974 Cygni (Nova Cygni 1992). The orbital period of 0.081263 +/- 0.000003 days places this classical nova just below the cataclysmic variable (CV) period gap. The modulation is driven by irradiation by the white dwarf (WD) heating one...

Zusammenfassung:We present the discovery of the photometric (orbital) period for V1974 Cygni (Nova Cygni 1992). The orbital period of 0.081263 +/- 0.000003 days places this classical nova just below the cataclysmic variable (CV) period gap. The modulation is driven by irradiation by the white dwarf (WD) heating one hemisphere of the red secondary and its aspect changes during orbital revolution. Published in The Astrophysical Journal, v431 n1 pL47-L49, 10 August 1994.
