Through the Spitzer IRAC GTO program, we have recently obtained
extremely sensitive mid-infrared images of young brown dwarfs
in the nearest star-forming regions. The spectral
energy distributions measured from these data provide
unprecedented measurements of the structure and lifetimes
protoplanetary disks around young brown dwarfs down to
10 times the mass of Jupiter.
