A Pre-Main Sequence Binary Viewed Through its Circumbinary Disk: A New Phase for KH 15D

Catrina M. Hamilton, Adi B. Chacko, George A. Carson +16

The binary T Tauri system, KH 15D, is poised to provide unprecedented detail of gas and ices located between 3-5 AU of its circumbinary disk over the next few years. We analy…
