The dust of interstellar comet 3I/ATLAS polarizes light differently than typical solar system comets
How does the dust of comet 3I/ATLAS, which came from outside the solar system, differ from the dust of solar system comets?When examining the vibration direction of light scattered by dust, 3I/ATLAS ...
太陽系の外からやってきた彗星3I/ATLASの塵は、太陽系の彗星の塵と何が違うのでしょうか。 塵が散らす光の振動方向を調べると、3I/ATLASには、典型的な太陽系の彗星とは異なる偏りが見られます。この偏りを測るのが「偏光観測」です。今回紹介する研究では、偏光に加えて反射光と赤外線も調べ、違いの理由を探りました。著者らは、小さな粒が集まってできる塵の構造が関係している可能性を指摘しています。 散乱 ...
