UVIS: Science Highlights
•
Determined phase function for C rings from UVIS FUV data for 175-190 nm. Fit both a power law and Minnaert phase
function with best fit from the Minnaert phase function. (Bradley)
Quarterly

<date>
Image of the Saturn environment in H Lya emission obtained from UVIS system scans in 2005 with the rings edge-on to the
spacecraft. The z-axis, passing through planet center perpendicular to the spin (y-)axis, is scaled to emission surface
brightness. Atomic hydrogen is evidently escaping from the top of the thermosphere into ballistic, orbiting, and escaping
components from the sunlit hemisphere. Rayleigh surface brightness values are indicated on the contour lines. x-y scale is in
Saturn radii, with positive values for north and astronomical west. From Shemansky et al 2009 . (Shemansky)
Quarterly

<date>
Image of the Saturn environment in one of several resonance features in electronic H2 band emission from the same image
cube as the previous slide. The resonance features do not appear in the aurora. The brightest feature is a ridge just south of the
rings, aligned with the atomic hydrogen plume shown in the previous slide. The resonance features are inferred to be
responsible for the escaping atomic hydrogen and heating of the thermosphere. Solar latitude: 22.3o S . From Shemansky et al.
2009. (Shemansky)
