LAMOST J202629.80+423652.0 is not a symbiotic star
  LAMOST J202629.80+423652.0 has been recently classified as a new symbiotic
star containing a long-period Mira, surrounded by dust (D-type) and displaying
in the optical spectra high ionization emission lines, including the
Raman-scattered OVI at 6825 Ang. We have observed LAMOST J202629.80+423652.0
photometrically in the BVRI bands and spectroscopically over the 3500-8000 Ang
range. We have found it to be a normal G8IV sub-giant star, deprived of any
emission line in its spectrum, and reddened by E(B-V)=0.35 mag. Combining our
photometry with data from all-sky patrol surveys, we find LAMOST
J202629.80+423652.0 to be non variable, so not pulsating as a Mira. We have
compiled from existing sources its spectral energy distribution, extending well
into the mid-Infrared, and found it completely dominated by the G8IV
photospheric stellar emission, without any sign of circumstellar dust. We
therefore conclude that LAMOST J202629.80+423652.0 is not a symbiotic star, nor
it is pulsating or been enshrouded in dust.
