BRITE observations of four targets in the 38-Cyg-III-2018 field and comparison with Kepler and TESS data

In 2019, we received long time-series photometric observations of bright (visual magnitude ~6) main-sequence A and B type stars from the BRITE satellites. The BRITE data were requested to follow up on four A- and B-type stars in the field-of-view of the NASA Kepler mission, two of which had been observed by Kepler as a result of Director’s Discretionary Time proposals.  Data is available for one of these targets from the NASA TESS mission.

Our goal was to discover and characterize pulsations in these targets for asteroseismology.  We present results on the light curves and pulsation frequencies, comparing results from BRITE data and Kepler or TESS data, when available.  Follow-up observations and analysis will be needed to constrain stellar parameters and to understand the nature of the variability.
