| | AN ULTRAVIOLET SPECTROSCOPIC STUDY OF THE WHITE DWARF IN U GEMINORUM DURING QUIESCENCE (Site not responding. Last check: 2007-11-05) |
 | | During quiescence the photospheric radiation of the exposed white dwarf dominates the ultraviolet (Kiplinger, Sion and Szkody 1991,ApJ,366,569; Long et al.1993,ApJ,405,327). |
 | | The variations in absorption line strengths and continuum flux levels are analyzed as a function of both orbital phase and time of observation since the return to optical quiescence, by fitting the IUE spectra with a grid of high gravity, LTE, model atmospheres with solar composition (and fractional composition thereof)constructed with I. Hubeny's TLUSTY code. |
 | | Spectroscopic changes of the white dwarf associated with the accretion process are compared with theoretical simulations of disk accretion and implications are discussed. |
