Subaru Imaging of Asymmetric Features in a Transitional Disk in Upper Scorpius

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 $^{\circ}$, respectively. The disk is asymmetric, with one dip located at P.A.s of $\sim85^{\circ}$. 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.Comment: 21 pages, 3 figures, published 2012 November 7 by ApJL, typo correcte

瀬戸内海の高級魚！オニオコゼの種苗生産技術開発の現状

オニオコゼは関東～新潟以南の浅海の砂泥底に棲息する魚で、上品な味の白身が人気を呼ぶことから瀬戸内海、九州、日本海では沿岸漁業の貴重な収入源になっています。しかし、近年は漁獲量が減少し、漁業者からは稚魚 (以下、種苗) の放流による資源回復が切望される重要な栽培漁業対象種になっています。このため、西日本を中心とする関係機関は本種の種苗生産に取り組み、一部の機関では10万尾単位での生産が可能になりつつありますが、まだ安定した飼育技術を確立するまでには至っていません。このため、瀬戸内海区水産研究所では、本種の安定かつ効率的な種苗生産技術の開発に取り組んでいます。articl
