HST/UV periodic variations in the intermediate polar FO Aqr.

Abstract (from CDS):
A preliminary analysis of high temporal HST UV spectroscopy, as well as SAAO BVRI photometry, has revealed that FO Aqr, differently from all previous observations, has changed from a spin dominated to an orbital dominated variability, both in lines and continuum. The spectral dependence of the orbital continuum, however, has not changed with time. The periodical variations are discussed in terms of standard accretion models.
