Description:
VLA observations with a limiting spatial resolution of about 0.15 arcsec were attempted along with complementary observations of SiO emission using the three-element Hat Creek interferometer to determine an accurate position of the long-period variable (LPV) of the R Aquarii binary system. The observations indicate that the LPV wind is distorted by the photoionization of the hot campanion's accretion disk, that precession of the accretion disk may occur, and that the observed v = 1, J = 2-1 transition emanates from a circumbinary layer far removed from the position of the LPV itself.
