Coronagraphic imagery of the circumstellar disk around HD 169142 in H -band polarized intensity ( PI ) with Subaru/HiCIAO is presented .
The emission scattered by dust particles at the disk surface in 0 \farcs 2 \leq r \leq 1 \farcs 2 , or 29 \leq r \leq 174 AU , is successfully detected .
The azimuthally-averaged radial profile of the PI shows a double power-law distribution , in which the PIs in r = 29 - 52 AU and r = 81.2 - 145 AU respectively show r ^ { -3 } -dependence .
These two power-law regions are connected smoothly with a transition zone ( TZ ) , exhibiting an apparent gap in r = 40 - 70 AU .
The PI in the inner power-law region shows a deep minimum whose location seems to coincide with the point source at \lambda = 7 mm .
This can be regarded as another sign of a protoplanet in TZ .
The observed radial profile of the PI is reproduced by a minimally flaring disk with an irregular surface density distribution or with an irregular temperature distribution or with the combination of both .
The depletion factor of surface density in the inner power-law region ( r < 50 AU ) is derived to be \geq 0.16 from a simple model calculation .
The obtained PI image also shows small scale asymmetries in the outer power-law region .
Possible origins for these asymmetries include corrugation of the scattering surface in the outer region , and shadowing effect by a puffed up structure in the inner power-law region .
