A model fit to the spectral energy distribution of this object indicates a ~7 AU inner disk hole that contains a small amount of optically thin dust. In previous studies, CVSO 224 had been classified as a weak-line T Tauri star based on its Halpha equivalent width, but here we find an accretion rate of 7x10^-11 Msun/yr based on high-resolution Hectochelle data. CVSO 224's low mass accretion rate is in line with photoevaporative clearing theories. Howev","authors_text":"B. Sargent, C. Briceno, C. Espaillat, D. M. Watson, J. Hernandez, J. Muzerolle, L.
