We investigate the possibility to detect giant planets that are stillembedded in young circumstellar disks. Based on models with different stellar,planetary, and disk masses, and different radial positions of the planet weanalyze the resulting submillimeter appearance of these systems. We find thatthe influence of the planet on the spectral energy distribution could not bedistinguished from that of other disk parameters. However, dust reemissionimages of the disks show that the hot region in the proximity of a youngplanet, along with the gap, could indeed be detected and mapped with theAtacama Large Millimeter Array in the case of nearby circumstellar disks(d<100pc) in approximate face-on orientation.Comment: ApJ, in pres
