Abstract
The origin and evolution of circumstellar disks is one of the main
scientific quests intimately related with planetary formation since
disks are known to be planetary nurseries. A study of statiscally
significant young stellar populations in differing evolutionary stages
and astrophysical environments can provide fundamental tests for
theories of disk and planet formation. We are presently conducting a
systematic broadband infrared wavelength study of ten young clusters of
different ages in order to compare their circumstellar disk frequency.
In this talk we report our results of JHK photometry of two nearby
clusters in our sample L1654 and NGC 2547. Having a considerable age
difference (1-5 and 14 Myr respectively) it is expected that NGC 2547
shows a smaller frequency of disks according to present theories of disk
dissipation and planetary formation.
