Phrase: 59 Cygni as a spectroscopic binary | Statement: [Williamina Fleming, discovered, 59 Cygni as a spectroscopic binary]

Target entity: 59 Cygni as a spectroscopic binary
Context triple: [Williamina Fleming, discovered, 59 Cygni as a spectroscopic binary]

• A. Plaskett’s Star
  Plaskett’s Star is a massive, highly luminous spectroscopic binary system composed of two very hot O-type stars, notable as one of the most massive known binary star systems in the Milky Way.
• B. On the Relations between the Spectra and Other Characteristics of the Stars
  "On the Relations between the Spectra and Other Characteristics of the Stars" is a landmark 1914 paper by Henry Norris Russell that helped establish the relationship between stellar spectral type, luminosity, and other properties, laying groundwork for the Hertzsprung–Russell diagram and modern stellar astrophysics.
• C. Harvard spectral classification of stars
  The Harvard spectral classification of stars is an early 20th-century system that categorizes stars by their spectral characteristics and surface temperatures into types O, B, A, F, G, K, and M, forming the basis of modern stellar classification.
• D. The Motion of Stars
  The Motion of Stars is a 1910 silent short film directed by D.W. Griffith that explores astronomical themes through early cinematic techniques.
• E. Gamma Microscopii
  Gamma Microscopii is a yellow giant star in the southern constellation Microscopium, notable as its most luminous visible member.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: 59 Cygni as a spectroscopic binary
Triple: [Williamina Fleming, discovered, 59 Cygni as a spectroscopic binary]

59 Cygni as a spectroscopic binary is a stellar system in the constellation Cygnus whose binary nature is revealed through periodic Doppler shifts in its spectral lines rather than direct visual separation.
