  As long as astronomers have searched for exoplanets, the intrinsic
variability of host stars has interfered with the ability to reliably detect
and confirm exoplanets. One particular source of false positives is the
presence of stellar magnetic or chromospheric activity that can mimic the
radial-velocity reflex motion of a planet. Here we present the results of a
photometric data analysis for the known planet hosting star, BD-06 1339,
observed by the Transiting Exoplanet Survey Satellite (TESS) during Sector 6 at
2 minute cadence. We discuss evidence that suggests the observed 3.9 day
periodic radial velocity signature may be caused by stellar activity rather
than a planetary companion, since variability detected in the photometric data
are consistent with the periodic signal. We conclude that the previously
reported planetary signature is likely the result of a false positive signal
resulting from stellar activity, and discuss the need for more data to confirm
this conclusion.
