dc.description.abstractWe present H- and K-s-bands observations of the LkH alpha 330 disk with a multi-band detection of the large gap and spiral-like structures. The morphology of the outer disk (r similar to 0."3) at PA = 0 degrees-45 degrees and PA degrees = 180-290 degrees is likely density wave-induced spirals, and comparison between our observational results and simulations suggests a planet formation. We have also investigated the azimuthal profiles at the ring and the outer-disk regions as well as radial profiles in the directions of the spiral-like structures and semimajor axis. Azimuthal analysis shows a large variety in wavelength and implies that the disk has non-axisymmetric dust distributions. The radial profiles in the major-axis direction (PA = 271 degrees) suggest that the outer region (r >= 0."25) may be influenced by shadows of the inner region of the disk. The spiral-like directions (PA = 10 degrees and 230 degrees) show different radial profiles, which suggests that the surfaces of the spiral-like structures are highly flared and/or have different dust properties. Finally, a color map of the disk shows a lack of an outer eastern region in the H-band disk, which may hint at the presence of an inner object that casts a directional shadow onto the disk.en_US
