Evidence of asymmetries in the Aldebaran photosphere from multi-wavelength lunar occultations

A. Richichi, V. Dyachenko, A. K. Pandey +6

We have recorded three lunar occultations of Aldebaran (AlfTau) at different telescopes and using various band-passes, from the ultraviolet to the far red. The data have been analy…
