Protostar forming in the nebula L1527, as captured by the Webb Telescope
Summary
[edit]| Description |
Français : Structures de poussière entourant une protoétoile à l'intérieur de la nébuleuse L1527 IRS, telles que capturées par NIRCam sur le télescope spatial James Webb. Notez la forme générale du sablier, ainsi que la différence de courbure entre la paire de limites supérieure gauche-inférieure droite et la paire de limites supérieure droite-inférieure gauche. Des éruptions stellaires occasionnelles ont formé des formes en forme de bulles dans la partie centrale supérieure. Les zones bleues représentent des formations de poussière plus fines, les zones orange plus épaisses. La ligne rose foncé au milieu est le bord du disque formatif de la protoétoile.
English: The protostar L1527, shown in this image from the NASA/ESA/CSA James Webb Space Telescope, is embedded within a cloud of material (the thin pink line in the center of the hourglass shape) that is feeding its growth. Material ejected from the star has cleared out cavities above and below it, whose boundaries glow orange and blue in this infrared view. The upper central region displays bubble-like shapes due to stellar ‘burps,’ or sporadic ejections. Webb also detects filaments made of molecular hydrogen that has been shocked by past stellar ejections. Intriguingly, the edges of the cavities at upper left and lower right appear straight, while the boundaries at upper right and lower left are curved. The region at lower right appears blue, as there’s less dust between it and Webb than the orange regions above it. Deutsch: Staubstrukturen, die einen Protostern im Nebel L1527 umgeben, aufgenommen von NIRCam am James-Webb-Weltraumteleskop. Beachten Sie die allgemeine Sanduhrform sowie den Unterschied in der Krümmung zwischen dem oberen linken und unteren rechten Begrenzungspaar und dem oberen rechten und unteren linken Begrenzungspaar. Gelegentliche Sternausbrüche haben im oberen mittleren Abschnitt blasenartige Formen gebildet. Blaue Bereiche stellen dünnere Staubformationen dar, orange Bereiche dickere. Die dunkelrosa Linie in der Mitte ist der Rand der Formationsscheibe des Protosterns.
日本語: ジェームズ ウェッブ宇宙望遠鏡の NIRCam が捉えた、星雲 L1527 内の原始星を取り囲む塵の構造。 全体的な砂時計の形と、境界の左上と右下のペアと、右上と左下の境界のペアの間の曲率の違いに注意してください。 時折の星の噴火により、中央上部に泡のような形が形成されました。 青い領域は薄い塵の形成を表し、オレンジ色の領域は厚いことを表しています。 中央の濃いピンク色の線は、原始星の形成円盤の縁です. |
