In the stellar forming region NGC 2264 there are objects catalogued ashosting a transitional disk according to spectrum modeling. Four members ofthis set have optical and infrared light curves coming from the CoRoT andSpitzer telescopes. In this work, we try to simultaneously explain the lightcurves using the extinction of the stellar radiation and the emission of thedust inside the hole of a transitional disk. For the object Mon-296, we weresuccessful. However, for Mon-314, and Mon-433 our evidence suggests that theyhost a pre-transitional disk. For Mon-1308 a new spectrum fitting using the 3Dradiative transfer code Hyperion allows us to conclude that this object hosts afull disk instead of a transitional disk. This is in accord to previous work onMon-1308 and with the fact that we cannot find a fit for the light curves usingonly the contribution of the dust inside the hole of a transitional disk.
