Constraints on the Tropospheric Cloud Structure of Jupiter from Spectroscopy in the 5-µm Region: A Comparison between Voyager/IRIS, Galileo-NIMS, and ISO-SWS Spectra

Carlson, R. W.; Drossart, P.; Encrenaz, Th. +2 more

The 5-µm window in the spectrum of Jupiter is one of the few regions that gives access to the vertical structure of the troposphere between pressure levels of approximately 4 and 8 bar. Voyager/IRIS spectra obtained in 1979 during the Voyager flybys have been analyzed intensively over the past two decades. Most of these analyses concluded on…

ISOPHOT Polarization Measurements of the Asteroids (6) Hebe and (9) Metis at 25 µm

Erikson, A.; Müller, T. G.; Klaas, U. +1 more

The subsurface thermal IR emission of asteroids becomes linearly polarized when scattered across the surface. The disk integrated mid-IR Stokes parameters are computed by extending the new thermophysical model by Lagerros (1996, Astron. Astrophys.315, 625-632; 1998, Astron. Astrophys.332, 1123-1132). The small scale surface roughness is approximat…
