of further investigation is the temporal changes in the saturnian hazes and clouds. Using the data set presented in Ortiz et al. (Icarus 117, 328–344, 1995) we further analyze some of the most outstandIn a recent paper, Ortiz et al. (1993) analyzed 1991 Saturn ing changes from 1991 to 1993 in the saturnian atmosphere. For images at methane bands and nearby continuum wavethis purpose, limb-to-limb reflectivity scans at planetographic lengths between 0.6 and 0.96 em. We then pointed out latitudes 08, 108, 208, 408, and 708 have been studied in terms temporal changes in Saturn’s clouds by comparing our of multiple scattering radiative transfer models. The large results with those of West et al. (1982), and stressed the changes in reflectivity and methane absorption at equatorial need for a more frequent and systematic study in order to latitudes from 1991 to 1993 are attributed to a considerable find out the timescale of these changes and also to identify increase in the aerosol abundance at different levels within the the physical processes which lead to them. In a subsequent extended tropospheric haze. 1996 Academic Press, Inc. work, Ortiz et al. (1995) presented and compared some results from four different data sets over a 3-year period using the same instrumentation and reduction techniques.

The Role of Clouds in Brown Dwarf and Extrasolar Giant Planet Atmospheres
Clouds and hazes are important throughout our solar system and in the atmospheres of brown dwarfs and extrasolar giant planets. Among the brown dwarfs, clouds control the colors and spectra of the L-dwarfs; the disappearance of clouds helps herald the arrival of the T-dwarfs. The structure and composition of clouds will be among the first remote-sensing results from the direct detection of extr...
متن کاملSpoke Formation Under Moving Plasma Clouds
Goertz and Morfill (1983) propose that spokes on Saturn’s rings form under radially moving plasma clouds produced by meteoroid impacts. We demonstrate that the speed at which a plasma cloud can move relative to the ring material is bounded from above by the difference between the Keplerian and corotation velocities. The radial orientation of new spokes requires radial speeds that are at least a...

متن کاملA Near-infrared Transmission Spectrum for the Warm Saturn Hat-p-12b
We present a HST WFC3 transmission spectrum for the transiting exoplanet HAT-P-12b. This warm (1000 K) sub-Saturn-mass planet has a smaller mass and a lower temperature than the hotJupiters that have been studied so far. We find that the planet’s measured transmission spectrum lacks the expected water absorption feature for a hydrogen-dominated atmosphere, and is instead bestdescribed by a mode...
