1 Otero, Sebastian Alberto Before 2014,WOH G64 was classified as a late M-type RSG (M7.5(I)e), had Mira-like variability (P= 886 d., range V= 16.7-19.0), and a very red color, V-Ic ~5. After 2015, the star lost its periodicity, had a bluer color (V-Ic ~3.2), and exhibited spectral emission features typically seen in B[e] stars. WOH G64 is a massive symbiotic system where the RSG has dramatically transitioned to a Yellow Hypergiant and has a B-star companion (2024arXiv241119329M).
