sigma Octantis.

REA B.

Abstract (from CDS):

We examine data from three Sectors of observations from NASA's Transiting Exoplanet Survey Satellite (TESS) for the delta Scuti star sigma Octantis = HD 177482. We were unable to conclude that it is a hybrid delta Sct/gamma Dor variable as reported in earlier literature because the evidence for the presence of active gamma Dor frequencies was absent from one Sector's data and only weakly statistically significant in the other two. We report that several of the delta Sct frequencies showed statistically significant amplitude modulation between the three TESS Sectors.
