Astronomy:List of stars that dim oddly

From HandWiki
Short description: Stars that dim in an odd way


Artist's concept of an "uneven ring of dust" orbiting KIC 8462852, also known as Tabby's Star

This list of stars that dim oddly is a table of stars that have been observed to darken and brighten and don't appear to be eclipsing binaries or intrinsic variables. It's based on studies searching for analogs of Tabby's Star.[1][2]

The listing here is ordered alphabetically.
