Abstract:
From subarcsec-seeing infrared images and spectra in the K and H bands, we present reflectivities and limb-darkening results for two of the hazy regions generated during the SL-9 collision. These highly reflective impact areas at infrared methane wavelengths have been studied in terms of multiple scattering radiative models. The results for both the H and D/G impact remnants show that a considerable amount of particles have been injected in Jovian stratospheric levels from similar to 1 mbar to the upper level of the assumed Jovian tropospheric NH3 ice haze (at similar to 350 mbar). Our models suggest a concentration of small particles, with mean radius of 0.15 mu m for a real refractive index of 1.7. The imaginary refractive indices are in the range 1x10(-4) to 1x10(-3). For the H impact region, absorption at 2.0 mu m is enhanced compared to unperturbed regions at the same scattering geometry. This enhancement is not observed in the older D/G complex.
