Is V426 Ophiuchi really an intermediate polar ?
Abstract
The dwarf nova V426 Oph has been proposed as an intermediate polar with a report of a 60-min period in the X-ray band. Optical photometry and spectroscopy show no evidence for such a period. Additionally, reanalysis of the X-ray data shows that the 60-min period is not significant and that the variability is consistent with flickering. Overall, no evidence has been found that V426 Oph is an intermediate polar.
