Chandra X-ray results on V426 Ophiuchi
Abstract
From a 45ks Chandra observation of V426 Oph we have obtained high-resolution X-ray spectra at moderate signal-to-noise, and a good quality, uninterrupted lightcurve. The spectra are reasonably fit with a cooling flow model, similar to EX Hya and U Gem. Our analysis of the Chandra and additional X-ray/optical lightcurves reveals a persistent modulation at 4.2 hr from 1988 to 2003, likely the white dwarf spin period indicating an intermediate polar nature for V426 Oph.
