THE RED RECTANGLE: ITS SHAPING MECHANISM AND ITS SOURCE OF ULTRAVIOLET PHOTONS
THE RED RECTANGLE: ITS SHAPING MECHANISM AND ITS SOURCE OF ULTRAVIOLET PHOTONS
The proto planetary Red Rectangle (RR) nebula is powered by HD 44179, a spectroscopic binary (P = 318 d), in which a luminous post-asymptotic giant branch (AGB) component is the primary source of both luminosity and current mass loss. Here, we present the results of a seven-year, eight-orbit spectroscopic monitoring …
