DQ Herculis in Profile: Whole Earth Telescope Observations and Smoothed Particle Hydrodynamics Simulations | | M. A. Wood

26 Sep 1999 | | Subject: | astro-ph | | Abstract: | DQ Herculis was the Summer 1997 WET northern-hemisphere primary target. The O-C phase diagram of the 71-s signal reveals out-of-eclipse phase variations resulting from the self eclipses of a nearly edge-on, non-axisymmetric disc. We work the forward 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 to 89.7 degrees. | | Source: | arXiv, astro-ph/9909431 | | Services: | Forum | Review | PDF | Favorites | |
