First, in each cluster, averaged over the spread of age, we investigate how disk lifetime is dependent on stellar mass. The general relation in IC348 and OrionA is that primordial disks around intermediate-mass stars (2-5M_{sun}_) evolve faster than those around loss-mass stars (0.1-1M_{sun}_), which is consistent with previous results. However, considering only low-mass stars, we do not find a significant dependence of disk frequency on stellar mass. These results can help to better constrain theories on gas giant planet formation timescales. Second, in the OrionA molecular cloud, in the mass range of 0.35-0.7M_{sun}_, we provide the most robust evidence to date for disk evolution within a single cluster exhibiting modest age spread. By using surface gravity as an age indicator and employing 4.5{mu}m excess as a primordial disk diagnostic, we observe a trend of decreasing disk frequency for older stars. The detection of intra-cluster disk evolution in NGC1333 and IC348 is tentative, since the slight decrease of disk frequency for older stars is a less than 1{sigma} effect.2018ApJ...869...72Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/869/72CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/332 : c2d Spitzer final data release (DR4) (Evans+, 2003)I/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AJ/111/1964 : JHK photometry of NGC1333 (Lada+, 1996)J/A+A/337/403 : Low-mass stars evolutionary models (Baraffe+ 1998)J/AJ/116/1816 : JHKLMNOPQ photometry in Orion cluster (Hillenbrand+, 1998)J/ApJ/593/1093 : IC 348 membership (Luhman+, 2003)J/AJ/127/1131 : NGC 1333 low-mass stars infrared photometry (Wilking+, 2004)J/AJ/129/856 : Herbig Ae/Be stars nearby OB associations (Hernandez+, 2005)J/ApJ/651/L49 : Upper Sco OB association IRAC obs.
