The two bright lobes are bisected by a central dust lane (the dust disk) which is obviously identified in infrared observations. The polarization maps of two main lobes<br \/>\nshow symmetric pattern about a single illuminating source in the main eastern lobe. The low polarization degrees of the main inner lobes (< 10 percent in J,H and Ks wavelengths) show this bipolar nebula is an combination of emission and reflection nebulosity  .\nIn addition, the position of trapezium stars in optical wavelengths, radio continuum observations and IRAS source are agreed with these infrared observations.\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u3010\u65e5\u6642\u30112\u670822\u65e5(\u6c34)\u300010:30\uff5e12:00 \u3010\u5834\u6240\u3011\u56fd\u7acb\u5929\u6587\u53f0\u30fb\u4e09\u9df9\u3000\u4e2d\u592e\u68df\uff08\u5317\uff091\u968e \u8b1b\u7fa9\u5ba4 \u3010\u767a\u8868\u8005\uff08\u656c\u79f0\u7565\uff09\u3011Sukom Amnart\uff08\u7dcf\u7814\u5927 D1\u30fb\u4e09\u9df9\u3001\u6307\u5c0e\u6559\u54e1 : \u7530\u6751\u3000\u5143\u79c0\uff09 \u3010\u30bf\u30a4\u30c8\u30eb\u3011A Near [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,5],"tags":[],"class_list":["post-113","post","type-post","status-publish","format-standard","hentry","category-6","category-5"],"_links":{"self":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/113","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=113"}],"version-history":[{"count":0,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=\/wp\/v2\/posts\/113\/revisions"}],"wp:attachment":[{"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=113"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=113"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/guas-astronomy.jp\/weblog\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=113"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
