Study of the IR-excess supergiant HD 331319
We report the discovery of brightness variability in the IR-excess earlyF supergiant HD 331319, a candidate post-AGB star. Over three years ofsystematic U BV observations, the star showed low-amplitude (up to in V)quasi-periodic brightness variations on a time scale of ˜45 days. Apreliminary analysis of our photometry indicates that HD 331319 andother typical post-AGBF supergiants have a similar pattern ofvariability. A study of the extinction toward HD 331319 leads us toconclude that the fraction of the circumstellar extinction is small forthis star. We present low-resolution spectroscopy for HD 331319 anddiscuss the spectral classification of post-AGB F supergiants using HD331319, HD 161796, HD 187885, and HD 56126 as examples.
