Connecting Young Star Magnetospheres & Circumstellar Disks

As with many of these science stories, including Quasars, Fermi, ALMA, oh my!, one overarching question is how new, especially panchromatic data can be folded together to deduce new physical connections and processes.

Is there a relationship between the magnetosphere and the disk of young stars? This topic has been frequently in the literature. Past studies have been focused on correlations in emission in different optical bands, e.g., U, B, V optical photometry from a single catalog. With recent surveys (IR, X-ray) this has become wider in scope as we better understand the physics of young stars. If young stars have IR excess due to circumstellar disks and young stars emit X-rays due hot accretion spots and from enhanced magnetic activity due to rapid rotation:

• Can we deduce a relationship between the disk flux and X-ray flux that might reveal or constrain their coupling?
