How this entity was disambiguated
This entity first appeared as the object of triple T19970151 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

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.
