Fuse Observations of U Geminorum during Outburst and Decline

We have obtained FUV (904 – 1187 Å) spectra of U Gem in outburst with FUSE. Three of the observations were acquired during the plateau phase of the outburst, while the fourth was obtained during late outburst decline. The plateau spectra have continuum shapes and fluxes that are approximated by steady-state accretion disk model spectra with ṁ ≃ 7 × 10 M⊙ yr… CONTINUE READING
