Target entity: O4-type stars
Context triple: [IC 1805, hasMassiveMembers, O4-type stars]
  • A. Wolf–Rayet stars
    Wolf–Rayet stars are extremely hot, massive, and luminous evolved stars characterized by powerful stellar winds and strong emission lines from heavy elements in their spectra.
  • B. RV Tauri
    RV Tauri is a class of luminous pulsating variable stars, typically post-asymptotic giant branch objects, characterized by alternating deep and shallow minima in their light curves.
  • C. T Tauri stars
    T Tauri stars are very young, low-mass pre–main-sequence stars still contracting and often surrounded by protoplanetary disks, commonly found in star-forming regions.
  • D. Cepheid
    Cepheid is a molecular diagnostics company known for its rapid, automated PCR-based testing systems used in clinical and research settings.
  • E. Cepheid variables
    Cepheid variables are pulsating stars whose regular brightness variations make them crucial standard candles for measuring cosmic distances and mapping galactic structure.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
