We report direct observational evidence for a latitudinal dependence of dust cloud opacity in ultracool dwarfs. indicating that equatorial latitudes are cloudier than polar latitudes. These results are based on a strong positive correlation between the viewing geometry and the mid-infrared silicate absorption strength in mid-L dwarfs using mid-infrared spectra from the Spitzer Space T... https://www.infonoticiasgandia.com/product-category/mixing-bowls/
