Circumstellar Disk Lifetimes In Numerous Galactic Young Stellar Clusters
Alexander J. W. Richert, Konstantin V. Getman, Eric D. Feigelson +5
Photometric detections of dust circumstellar disks around pre-main sequence (PMS) stars, coupled with estimates of stellar ages, provide constraints on the time available for plane…
