Interferometry on Mira in the mid-infrared: cyclic variability of the continuum diameter and the effect of spectral lines on apparent size.


Abstract (from CDS):

The size and variability of the continuum photosphere of ο Ceti have been measured with 11 µm heterodyne interferometry to an accuracy of about 1%. Narrow bandwidths (∼0.17 cm–1) were used to avoid spectral lines and measure continuum only. The resulting 11 µm diameter of ο Cet is larger than the previously measured visible and near-infrared sizes. In addition, variations in the diameter with phase and a possible elongation have been observed. Visibilities were also measured at wavelengths known to contain strong H2O spectral contamination, giving larger apparent stellar sizes and information on the distribution of hot H2O gas.
