V518 Carinae was discovered to change in brightness after analysis ofHipparcos photometry.[11] The amplitude of the variations seen is 0.2magnitudes, with possible periods of 100 and 971 days.[12] It is classified as aγ Cassiopeiae variable.[13][4]
V518 Carinae is also aBe star, a hot star withemission lines in its spectrum due to a disk of material around the star. Be stars that show irregular brightness changes due to the disk are grouped as γ Cassiopeiae variables. V518 Carinae is known to produce disk outbursts lasting several hundred days.[16]
