As far as we know, the pair consists of a rapidly rotating G-type star and a hot star, which is responsible for the ionization of the nebula. The rotation period of the G-type star is 5.95 days and the orbital period of the binary is now known to be $\\sim$2700 days, one of the longest in central star of planetary nebulae. The spectrum of the G central star shows a complex H$\\alpha$ double-peaked profile which varies with very short time scales, also reported in other central stars of planetary nebulae and whose origi","authors_text":"A.
