本文指出SPHEREx图像中VY Canis Majoris周围的壳层在其他亮星相似位置也出现,判定其为探测器伪影而非天体物理结构。
AI 中文摘要
最近,有报道称在SPHEREx任务的图像中,明亮超巨星VY Canis Majoris周围存在一个巨大的壳层。我们报告在SPHEREx Band 1图像中,其他明亮恒星在相似位置也出现了类似的壳层,这表明该壳层并非天体物理现象,而是探测器伪影。
英文摘要
Recently, the presence of a large shell around the bright hypergiant star VY Canis Majoris was reported in images from the SPHEREx mission. We report similar shells around other bright stars at similar locations in SPHEREx Band 1 images, suggesting that this shell is not astrophysical but instead a detector artifact.
