This is a list of semiregular variable stars. Variability ranges are taken from the General Catalogue of Variable Stars (GCVS) where these are visual magnitudes, otherwise from the International Variable Star Index (VSX). Spectral types are taken from the GCVS, which may differ from more recent MK spectral types but often defines a range.(This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.)
