【 摘 要 】

The determination of timescales associated with planetary formation and circumstellar disk evolution requires large samples of stars having diverse environments and ages. Such a sample can be obtained using the Sloan Digital Sky Survey as it is systematically mapping one-quarter of the entire sky providing photometric data on over 100 million objects in five passbands.
