Phrase: Galactic rotation | Statement: [Jan Oort, knownFor, Galactic rotation]

Target entity: Galactic rotation
Context triple: [Jan Oort, knownFor, Galactic rotation]

• A. Schwarzschild method in galactic dynamics
  The Schwarzschild method in galactic dynamics is a numerical orbit-superposition technique used to construct self-consistent models of galaxies and infer their mass distributions, including dark matter and central black holes.
• B. 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.
• C. Galactic thin disk
  The Galactic thin disk is the relatively flat, rotating component of the Milky Way where most of its young to middle-aged stars, gas, and spiral arms are concentrated.
• D. Milky Way stellar halo
  The Milky Way stellar halo is a vast, diffuse, roughly spherical population of old, metal-poor stars and dark matter that surrounds the Milky Way’s disk and bulge, extending far into its outer regions.
• E. Gould Belt
  The Gould Belt is a nearby, partial ring of young stars, gas, and star-forming regions tilted to the Milky Way’s plane and encompassing many of the bright constellations visible from Earth.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Galactic rotation
Triple: [Jan Oort, knownFor, Galactic rotation]

Galactic rotation is the large-scale orbital motion of stars and gas around the center of a galaxy, revealing its mass distribution and the presence of dark matter.
