TRANSITIONAL DISKS AROUND YOUNG LOW MASS STARS
A population of young circumstellar disks have di erent Spectral Energy Distributions (SEDs) with respect to typical disks, showing a decit of emission in the near-IR and an excess at mid-IR wavelengths. These SEDshave been interpreted as produced by disks with inner holes, which have been classied...

| Resumo: | A population of young circumstellar disks have di erent Spectral Energy Distributions (SEDs) with respect to typical disks, showing a decit of emission in the near-IR and an excess at mid-IR wavelengths. These SEDshave been interpreted as produced by disks with inner holes, which have been classied as \Transitional Disks". These disks are considered the evolutionary link between the full disks typically found around the young T Tauri and Herbig Ae stars, and the debris disks, found around some main sequence stars. In this contribution we summarize the observed/inferred characteristics of these transitional disks and also some of the models proposed to explain their peculiar geometry. |
