Abstract

The star HD 147379 was recently announced as a host of a low-mass exoplanet by Reiners et al. (2017). That announcement included a discussion of the possible detection of a periodic signal in the radial velocity observations around 21.1 days, which was interpreted as rotational variability of the star. We have examined the light curve of this star as observed by the KELT transit survey, and we find a significant periodic signal in the light curve of 22.0064 days, supporting the interpretation of Reiners et al. (2017) of the rotational variation of the star.
