Triple

Target class: radiation pressure limit
Context triple: [Eddington limit, instanceOf, radiation pressure limit]

• A. physical limit chosen
  A physical limit is a fundamental boundary imposed by the laws of nature that constrains how large, small, fast, or energetic any physical process or quantity can be.
• B. radiative transition coefficient
  The radiative transition coefficient is a parameter that quantifies the probability per unit time that an excited quantum state will spontaneously emit radiation and transition to a lower energy state.
• C. law of black-body radiation
  The law of black-body radiation describes how an idealized object emits electromagnetic radiation with an intensity and spectrum that depend solely on its temperature, as quantified by Planck’s radiation formula.
• D. Einstein coefficient
  The Einstein coefficient is a parameter in quantum theory that quantifies the probability per unit time of spontaneous or stimulated emission or absorption of radiation by an atom or molecule transitioning between energy levels.
• E. rotational instability in stars
  Rotational instability in stars is a dynamical condition where differential rotation or excessive spin causes internal layers to become unstable, leading to mixing, angular momentum redistribution, and potentially large-scale structural changes or mass loss.
• F. None of above.
