The transition disk around TCha ‣ Main characteristics of TCha: ‣ Solar-type star (G8), 7 Myr old ‣ Far-IR excess (cold dust) ‣ Near-IR excess (warm dust) ‣ Lack of mid-IR (no dust)
The transition disk around TCha ‣ Fact: the disk is dissipating. Question: how ‣ (hint: there is a strong near-IR excess) ‣ Circumbinary disk Single star (optical spectroscopy) ‣ Grain growth Would affect the innermost regions first ‣ Photo-evaporation Same as above ‣ Gap opened by a planet ‣ We need spatially resolved observations !
