Searching for flaring star-planet interactions in AU Mic TESS observations

AU Mic is a ~23 Myr old, early M dwarf, and the most actively flaring planet host detected to date. Its innermost companion, AU Mic b is a promising target for observations of flaring star-planet interactions (SPI). We used optical light curves of AU Mic obtained by TESS to search for signs of flaring SPI with AU Mic b in the form of excess flares. We find that additional ~50-100 d of TESS-like observations are required to confirm or reject the tentative signal of flaring star-planet interactions in the AU Mic system.
