Abstract

DQHerculis was the Summer 1997 WET northern hemisphere primary target. The O-C phase diagram of the 71s signal reveals out-of-eclipse phase variations resulting from the self eclipses of a nearly edge-on, non-axisymmetric disc. We investigate the problem of simulating DQ Herculis numerically, using the method of smoothed particle hydrodynamics (SPH), and from the time-averaged structure calculate the O-C phase variations as a function of inclination angle. The WET and SPH O-C phase variations match to a remarkable degree, and suggest a system inclination in the range 89.5° ≤ i ≤ 89.7°.
