AG CARINAE AND THE WR PHENOMENON IN LUMINOUS BLUE VARIABLES.
AG Car is a Luminous Blue Variable which recently evolved from Ale to Ofpe/WN9 in four years at about constant bolometric luminosity, while in the visual the star faded by two magnitudes. This change is probably associated with variable opacity of an unstable massive expanding envelope of a hot star. We discuss the main spectral features of the star and of its ring nebula, and the spectral variations.
