On the orbital period of the cataclysmic variable V592 Herculis.
MENNICKENT R.E., TAPPERT C., GALLARDO R., DUERBECK H.W. and AUGUSTEIJN T.
Abstract (from CDS):
We present a spectroscopic study of the long-recurrence-time dwarf nova V592 Herculis based on observations obtained during its August 1998 superoutburst. From the analysis of the radial velocities of the Hα emission line we find a most likely orbital period of 85.5±0.4min, but the 91.2±0.6min alias cannot be completely discarded. Both periods imply a very small period excess and supports the brown-dwarf like nature of the secondary star.
