The Centaurus X-3 research report connects an Indian institute with the physical process by which a compact star gains matter. Revise the research institution separately from the celestial object being investigated.
Correct answer: C — An accretion disk feeding the pulsar. The evidence supports an accretion disk and an associated stream of matter feeding the pulsar. This is a physical explanation for the emission behaviour, not a claim that researchers photographed an ordinary planetary ring. Distinguish the indirect inference from changing radiation signals from a direct surface image. Researchers at the Raman Research Institute studied the X-ray pulsar Centaurus X-3. Their analysis of changing secondary emission lines supported an accretion stream and disk around the pulsar. The finding is notable because direct stellar-wind capture is the more usual picture for high-mass X-ray binaries. Official source: Press Information Bureau
