Abstract
There are over 3900 eruptive variable stars within the General Catalog of Variable Stars. Of this number, over 550 are classified as uncertain within the various groups. Variable stars are identified as uncertain when a colon (:) follows the variable star type (e.g. FU: or RCB:) and indicates that insufficient information exists to definitively identify the variability type. It means that additional data must be collected and analyzed so that the star can be properly categorized.
Eruptive variables are stars varying in brightness because of violent processes and flares occurring in their chromosphere and coronae. The light changes are usually accompanied by shell events or mass outflow in the form of stellar winds or variable intensity and/or by interactions with the surrounding interstellar medium.
