Diffraction-limited spatial resolution of circumstellar dust shells at 10 micronsA new spatial array instrument has provided diffraction-limited mid-infrared intensity profiles of the type M supergiant stars Alpha Orionis and Alpha Scorpii, both of which are known to exhibit excess 10 micron radiation due to the presence of circumstellar dust shells. In the case of Alpha Ori, there is a marked asymmetry in the dust distribution, with peak intensity of dust emission a distance of 0.9 sec from the star.
