Abstract (from CDS):

We present a direct image of the innermost companion to the red giant δ Andromedae using the Stellar Double Coronagraph at the Palomar Observatory. We use a Markov Chain Monte Carlo based algorithm to simultaneously reduce the data and perform astrometry and photometry of the companion. We determine that the companion is most likely a main sequence K-type star and is certainly not the previously hypothesized white dwarf.
