Optical linear polarization in ultra cool dwarfs. A tool to probe dust in the ultra cool dwarf atmospheres
Aims. Recent studies have detected linear polarization in L dwarfs in the optical I band. Theoretical models have been developed to explain this polarization. These models predict higher polarization at shorter wavelengths. We discuss the polarization in the R and I band of 4 ultra cool dwarfs. Methods: We report linear polarization measurements of
Tata, R. et al.
