The shell around VY Canis Majoris in SPHEREx is likely an artifact
arXiv:2609.28612
Abstract
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.
