MWC656 has been reported as classical Be star with a black hole companion. Revisited spectral variability properties render this unlikely, with a hot subdwarf more probable.

  1. Complex spectral variability and hints of a luminous companion in the Be star + black hole binary candidate ALS 8814

    astro-ph.SR 2025-09 conditional novelty 6.0

    ALS 8814 is likely a double-lined binary with two luminous stars plus a possible third companion, not a Be star + black hole binary.
