The interaction between this rotating disk and the nascent star leads to the narrowing of material into jets that blast away from the magnetic poles of the would-be star. These stellar jets, detected in X-rays by Chandra, generate shock waves similar to those produced by supersonic jets."]},"metadata":[{"label":{"ja":["museum"]},"value":{"ja":["スミソニアン天体物理観測所"],"en":["Smithsonian Astrophysical Observatory"]}}],"rights":"http://creativecommons.org/publicdomain/zero/1.0/","thumbnail":[{"id":"https://3d-api.si.edu/content/document/3d_package:c3d10433-1b0a-44f3-9308-97d623195468/scene-image-low.jpg","type":"Image","format":"image/jpeg"}],"homepage":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/item/dg-tau-c3d104","type":"Text","label":{"ja":["詳細ページ"],"en":["Detail page"]},"format":"text/html"},{"id":"https://www.si.edu/object/dpo_3d_200121","type":"Text","label":{"ja":["出典"],"en":["Source"]},"format":"text/html"}],"rendering":[{"id":"https://3d-api.si.edu/content/document/3d_package:c3d10433-1b0a-44f3-9308-97d623195468/resources/DGTAU-150k-2048_std.glb","type":"Model","label":{"ja":["3Dモデル (GLB)"],"en":["3D model (GLB)"]},"format":"model/gltf-binary"}],"items":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1","type":"Scene","label":{"ja":["おうし座DG星（DG Tau）"],"en":["DG Tau"]},"backgroundColor":"#000000","items":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/page","type":"AnnotationPage","items":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/model","type":"Annotation","motivation":"painting","body":{"id":"https://3d-api.si.edu/content/document/3d_package:c3d10433-1b0a-44f3-9308-97d623195468/resources/DGTAU-150k-2048_std.glb","type":"Model","format":"model/gltf-binary"},"target":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1"}]}],"annotations":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/annotations","type":"AnnotationPage","items":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/annotation/7bzQsBr1l45Q","type":"Annotation","motivation":["commenting"],"body":{"type":"TextualBody","value":"あらゆる電流や変化する電場に伴う場であり、磁化した物体どうしが及ぼし合う影響を支配する。","label":"磁力線","language":"ja","format":"text/plain"},"target":{"type":"SpecificResource","source":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1","type":"Scene"}],"selector":[{"type":"PointSelector","x":74.4671097,"y":13.2716865,"z":-14.9330393,"normal":[0.2147037,0.4699928,0.8561595]}]}},{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/annotation/mvuBcYFzT4TT","type":"Annotation","motivation":["commenting"],"body":{"type":"TextualBody","value":"原始星は降着円盤に囲まれており、そこから星は質量を降着させる。","label":"降着円盤","language":"ja","format":"text/plain"},"target":{"type":"SpecificResource","source":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1","type":"Scene"}],"selector":[{"type":"PointSelector","x":5.9271384,"y":31.1227606,"z":26.3333002,"normal":[0.8715182,0.1361838,-0.4710732]}]}},{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1/annotation/aQX2fm8hjIlr","type":"Annotation","motivation":["commenting"],"body":{"type":"TextualBody","value":"円盤と回転する星の磁場との相互作用によって、落ち込む物質が収束（コリメート）され、恒星の磁極からジェットとして放出される。","label":"ジェット","language":"ja","format":"text/plain"},"target":{"type":"SpecificResource","source":[{"id":"https://archivebase.ldas.jp/na-kamura-1263/smithsonian-3d/api/iiif/4/dg-tau-c3d104/scene/1","type":"Scene"}],"selector":[{"type":"PointSelector","x":-58.0950365,"y":-17.4734389,"z":34.2135304,"normal":[0.1390291,0.2516444,0.9577818]}]}}]}]}]}
