Simultaneous Spitzer/Chandra Observation Of Young Stellar Objects In GGD 12-15 - Do X-ray Flares Produce Disk Afterglows?
Abstract
We present first results of a simultaneous 20h Spitzer/Chandra monitoring campaign of the young cluster GGD 12-15. By analyzing correlated X-ray and mid-IR variability on different timescales, we are testing 1) theoretical predictions of X-ray heating in circumstellar disks (in an analogy to reverberation mapping), and 2) whether disk accretion rates rise following stellar X-ray flares, as expected from disk accretion models. Focusing on simultaneous X-ray and mid-infrared observations and timescales of minutes to hours, this project is leveraging extensive mid-IR light curves obtained via the Spitzer Warm Mission program YSOVAR. Ancillary science includes the identification of weak-line T Tauri stars to study their mid-IR variability and the LX-rotation relation of protostars, using mid-IR periods.
