We have obtained FUSE spectra of several dwarf novae which reveal the properties of their accreting white dwarfs, their rates of accretion during quiescence and the nature of their boundary layer/inner disk regions including accretion belts on the white dwarfs. Among the systems for which preliminary results will be presented are BV Cen, WW Ceti, EY Cyg, SS Aur and VW Hyi. The contribution of these FUSE studies to our understanding of disk accretion physics will be emphasized within the context of the white dwarf and boundary layer.

Resumen

Resumen

Hemos obtenido espoctros do FUSE do varias novas cnanas, los cuales revelan las propiedades de sus enanas blancas aerocientes, sus ritmos do acreción duranto la etapa de quietud y la naturaleza de las regiones capa borde/disco interior incluyendo la zona do acreción en las enanas blancas. Entre los sistemas de los cuales presentamos resultados preliminares se encuentran BV Cen, WW Ceti, EY Cyg, SS Aur y VW Hyi. La oontribución de estos estudios realizados con FUSE a nuestro entendimiento de la física de los discos de acreción so enfatizará dentro dol contexto do la enana blaca y de la capa borde.
