WE PROPOSE TO GENERATE HIGH-PRECISION LIGHT CURVES FOR A SAMPLE OF ~500 YOUNG (1-5 MYR) INTERMEDIATE MASS STARS USING TESS FULL FRAME IMAGES AT 30-MINUTE CADENCE. GROUND-BASED OBSERVATIONS INFORM US THAT YOUNG BAF STARS ARE VARIABLE DUE TO A COMBINATION OF ACCRETION (FOR THE HERBIG AEBE OBJECTS) CIRCUMSTELLAR OBSCURATION AND STARSPOTS. HOWEVER DETAILED STUDIES OF THIS VARIABILITY AND ITS RELATIONSHIP TO THE STELLAR ENVIRONMENT HAVE NEVER BEEN CARRIED OUT ON A LARGE SCALE. WITH TESS WE WILL PERFORM THE FIRST COMPREHENSIVE ANALYSIS OF LIGHT CURVE MORPHOLOGY AMONG YOUNG INTERMEDIATE-MASS STARS AND ITS RELATIONSHIP TO MAGNETIC ACTIVITY AS WELL AS CIRCUMSTELLAR DISK PROPERTIES. THE RESULTS WILL BE COMPARED TO OUR PREVIOUS SPACE-BASED WORK ON LOW MASS K/M STARS IN YOUNG CLUSTERS.
