 Abstract: From all the stars formed inside the disk of young stars in the Galactic Centre, GCIRS7, a variable red supergiant in H and K bands, is by far the brightest of all of them. Using K band interferometric data (VLTI-GRAVITY), we measure uniform disk diameters around 20% times higher for wavelengths inside the CO absorption band compared to the continuum wavelengths, showing that a grey uniform disk model is not enough to reproduce the visibility curves of this star. A model based on a molecular spherical thin layer, already proven successful in other supergiant stars with similar spectral features, is implemented.
