We propose to study the young cluster GGD 12-15 to test theoretical predictions of X-ray heating in circumstellar disks, leveraging extensive mid-IR light curves to be obtained via our Spitzer Warm Mission program YSOVAR. With contemporaneous X-ray/mid-IR light curves, we will: 1) test if YSO X-ray and mid- IR variability are correlated, indicating that stellar X-rays significantly heat disks, and 2) test if disk accretion rates rise in the days and weeks following stellar X-ray flares, as expected from disk accretion models. Supplementary Spitzer observations will expand the scope of the program to shorter timescales. Ancillary science includes the identification of weak-line T Tauri stars to study their mid-IR variability and the LX-rotation of protostars, using mid-IR periods.
