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

This list of stars that dim oddly is a table of stars that have been observed to darken and brighten in an unusual manner. An overall study of such stars has been presented.[1][2]

The listing here is ordered alphabetically.
