Asymptotic giant branch and supergiant stellar diameters in the mid-infrared.


Abstract (from CDS):

The size of the continuum photospheres of α Ori, α Her, R Leo, and χ Cyg have been measured at 11 µm using heterodyne interferometry to accuracies as high as 1%. An assortment of narrow wavelength bands near 11 µm (each having a width ∼0.17cm–1) were used to avoid spectral lines. The resulting apparent diameters for α Ori and α Her are ∼30% larger than measured near-infrared sizes, whereas the Mira variables, R Leo and χ Cyg, have 11 µm apparent diameters roughly twice their reported near-infrared sizes. The complexities of interpretation are discussed.
