Description
Five well-known LBV stars in M33 were observed with the Multi-Pupil Fiber Spectrograph (MPFS) on the 6-m Russian telescope. We observed LBVs varA, varB, varC, var2 and var83. In three of them, var2, var83, varB, large-scale nebulae were found with sizes from 15 pc and larger. The nebula shapes are complex, like one-side tails or conical nebulae. They all are related to their LBV stars. In var2 and var83 stars we found radial velocity gradients 15-30 km/s across their nebulae. The stars varA and varC do not show extended nebulae, but nebular lines are certainty present in their spectra.
