Abstract

1 GRAVITY operates in the near-infrared K-band, i.e., with wavelengths between 2 and 2.5 μm. 2 PIONIER at the VLTI operates in the near-infrared H-band, i.e., with wavelengths between 1.5 and 1.8 μm. 3 MATISSE at the VLTI operates in the mid-infrared L-, M-, and N-bands, i.e., with wavelengths between 3 and 13 μm (Lopez et al., 2018). emission we measured with GRAVITY is located at positions smaller than the critical radius where the gap is expected to form as a result of to extreme-/farultraviolet/X-ray heating, the discs in our sample might be shaped by forming young planets rather than by depletion resulting from photoevaporation (Figure 2).

1 GRAVITY工作在近红外k波段，即波长在2 ~ 2.5 μm之间。VLTI的2 PIONIER工作在近红外h波段，即波长在1.5 ~ 1.8 μm之间。3 VLTI的MATISSE在中红外波段L-、M-和n波段工作，即波长在3到13 μm之间(Lopez等人，2018)。我们用重力测量的辐射位于小于临界半径的位置，在那里由于极紫外/远紫外/ x射线加热预计会形成间隙，我们样品中的圆盘可能是通过形成年轻行星而不是通过光蒸发导致的耗尽而形成的(图2)。
