Sakurai's object: a [WC] star in a new bipolar nebula after VLTP 2023 2023-09-04 Planetary Nebulae: A Universal Toolbox in the Era of Precision Astrophysics. IAU Symposium, Vol. 384. Proceedings of the International Astronomical Union; O. De Marco, A. Zijlstra, R. Szczerba, editors., Volume 19, pp. 444-446, 3 pp. Optical spectra of the Very Late Thermal Pulse (VLTP) object V4334 Sgr have shown a rapidly changing spectrum resulting from shocks in the outflow, which created a new bipolar nebula inside the old nebula. We see C II and C III emission lines emerging typical of a [WC 11-10]-type star. The strong increase of [O III] and [S III] emission lines indicate the possible onset of photoionisation in the new ejecta. NO stars: planetary nebulae VLTP bipolar van Hoof, P. A. M. Kimeswenger, S.
