Scientific paper

RY Scuti is a very massive and luminous evolved contact binary system surrounded by an unusual nebula that is only a few arcseconds in extent. We propose to obtain STIS spectra that will spatially resolve the spectrum of the star from its compact nebula for the first time. We also propose to duplicate privious WFPC2 H-Alpha images in order to investigate possible variability of the nebula resulting from eclipses in the binary system. Finally, we propose to image RY Scuti in SIII, which will probe the excitation conditions in the nebula when compared with our H-Alpha image.
