TESS Detections of Pulsations in Of?p Stars in the Magellanic Clouds.

HUBRIG S., JAYARAMAN R. and JARVINEN S.P.

Abstract (from CDS):

We used Transiting Exoplanet Survey Satellite observations to search for pulsations in six known Of?p stars in the Magellanic Clouds. We find evidence for pulsational variability in three Of?p stars: UCAC4 115-008604, OGLE SMC-SC6 237339, and AzV 220. Two of them, UCAC4 115-008604 and OGLE SMC-SC6 237339, have been reported to possess kG-order magnetic fields. The obtained results are important to constrain and improve stellar evolution models.
