Abstract

内容記述

We report high-resolution (0.07 arcsec) near-infrared polarized intensity images
of the circumstellar disk around the star 2MASS J16042165-2130284 obtained
with HiCIAO mounted on the Subaru 8.2 m telescope. We present our
H-band data, which clearly exhibits a resolved, face-on disk with a large inner
hole for the first time at infrared wavelengths. We detect the centrosymmetric
polarization pattern in the circumstellar material as has been observed in other
disks. Elliptical fitting gives the semimajor axis, semiminor axis, and position
angle (P.A.) of the disk as 63 AU, 62 AU, and -14 ◦, respectively. The disk is
asymmetric, with one dip located at P.A.s of 85◦. Our observed disk size agrees
well with a previous study of dust and CO emission at submillimeter wavelength
with Submillimeter Array. Hence, the near-infrared light is interpreted as scattered
light reflected from the inner edge of the disk. Our observations also detect
an elongated arc (50 AU) extending over the disk inner hole. It emanates at the
inner edge of the western side of the disk, extending inward first, then curving to
the northeast. We discuss the possibility that the inner hole, the dip, and the arc
that we have observed may be related to the existence of unseen bodies within
the disk.
