Discovery and photometric study of the new in-the-gap SU UMa dwarf nova Var 73 Dra.

ANTIPIN S.V. and PAVLENKO E.P.

Abstract (from CDS):

We present the discovery and the first investigation of the new dwarf nova Var 73 Dra. We carried out monitoring and time-resolved CCD observations in 2001 August-October and detected several normal outbursts with a recurrence time of about 7-8 days and one slightly brighter superoutburst with a ``plateau'' phase that lasted 13 days. Our photometry during the superoutburst clearly shows the presence of superhumps with the period 0.0954 (±0.0001) day (although the one-day alias period, 0.1053d, could not be ruled out). So, the observed features allow us to classify Var 73 Dra as a new SU UMa-type dwarf nova within the well-known gap of orbital period distribution of cataclysmic variables.
