On the reality of the spectroscopic orbit for R Aquarii.
Abstract
New velocities for the emission lines in R Aqr show that the system has not followed the orbit with a period of 26.7 years tentatively suggested by Merrill. The binary nature of the star and its enormous mass function of 16.5 solar masses are probably unreal. Evidence for mass loss with ionization and velocity increasing outward is presented.
