Query: Flickering in AGB stars: Probing the nature of accreting companions   Binary companions to asymptotic giant branch (AGB) stars are an important
aspect of their evolution. Few AGB companions have been detected, and in most
cases it is difficult to distinguish between main-sequence and white dwarf
companions. Detection of photometric flickering, a tracer of compact accretion
disks around white dwarfs, can help identify the nature of these companions. In
this work, we searched for flickering in four AGB stars suggested to have
likely accreting companions. We found no signs for flickering in two targets:
R~Aqr and V1016 Cyg. Flickering was detected in the other two stars: Mira and Y
Gem. We investigated the true nature of Mira's companion using three different
approaches. Our results for Mira strongly suggest that its companion is a white
dwarf.
