We assess the current membership of the nearby , young TW Hydrae Association and examine newly proposed members with the Wide-field Infrared Survey Explorer ( WISE ) to search for infrared excess indicative of circumstellar disks .
Newly proposed members TWA 30A , TWA 30B , TWA 31 , and TWA 32 all show excess emission at 12 and 22 \mu m providing clear evidence for substantial dusty circumstellar disks around these low-mass , \sim 8 Myr old stars that were previously shown to likely be accreting from circumstellar material .
TWA 30B shows large amounts of self-extinction , likely due to an edge-on disk geometry .
We also confirm previously reported circumstellar disks with WISE , and determine a 22 \mu m excess fraction of 42 ^ { +10 } _ { -9 } % based on our results .
