We present Spitzer observations of the young cluster NGC 2547, obtaining photometry at 3.6, 4.5, 5.8, 8.0, and 24 ЮМm, reaching significantly fainter infrared sensitivities than previous studies. With these observations, we investigate the disk frequency in this cluster. ... These objects form a well-defined family in the J-K,K-[3.6] color-color diagram. There is no evidence for excess emission at 3.6 ЮМm for cluster candidates with J-K . ... citations vs. year [year,citations] . ...

... Once a star loses its disk, it appears to be free to spin--up. ... By the time a star reaches the 1 day periods seen in some stars in Orion OB1a and b it must have lost their disk a relatively long time ago, and have spent only 5% of their post--birthline, PMS lifetime with a disk. ... These stars are roughly 10 Myr old. ... The most rapid rotation period among the Orion OB1a stars is about 0.7 days, which means that such a star would have lost its disk at an age of no older than 250,000 years. ...
