cds-question@unistra.frinfrared-photometrystellar-spectral-typespre-main-sequence-starsWe present photometry at 3-24{mu}m for all known members of the Upper Scorpius association ({tau}~11Myr) based on all images of these objects obtained with the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer. We have used these data to identify the members that exhibit excess emission from circumstellar disks and estimate the evolutionary stages of these disks. Through this analysis, we have found ~50 new candidates for transitional, evolved, and debris disks. The fraction of members harboring inner primordial disks is <~10% for B-G stars (M>1.2M_{sun}_) and increases with later types to a value of ~25% at >~M5 (M<~0.2 M_{sun}_), in agreement with the results of previous disk surveys of smaller samples of Upper Sco members. These data indicate that the lifetimes of disks are longer at lower stellar masses and that a significant fraction of disks of low-mass stars survive for at least ~10Myr. Finally, we demonstrate that the distribution of excess sizes in Upper Sco and the much younger Taurus star-forming region ({tau}~1Myr) is consistent with the same, brief timescale for clearing of inner disks.2012ApJ...758...31Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/758/31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)III/117 : MK Classifications of Close Visual Binaries (Corbally, 1984)J/MNRAS/431/3222 : UKIDSS GCS Upper Sco members (Lodieu, 2013)J/MNRAS/429/903 : New brown dwarf discs in Upper Scorpius (Dawson+, 2013)J/ApJ/756/133 : ScoCen debris disks around B- and A-type stars (Chen+, 2012)J/ApJ/749/79 : Transition disks.
