Target entity: MESA stellar evolution code
Context triple: [OPAL opacity project, usedBy, MESA stellar evolution code]
  • A. Numerical models of stellar interiors
    Numerical models of stellar interiors is a seminal astrophysics work by Martin Schwarzschild that developed theoretical and computational methods for understanding the internal structure and evolution of stars.
  • B. Structure and Evolution of the Stars
    Structure and Evolution of the Stars is a classic astrophysics textbook by Martin Schwarzschild that systematically develops the theory of stellar interiors and their life cycles.
  • C. Stellar Atmospheres
    "Stellar Atmospheres" is a landmark astrophysics work that fundamentally advanced understanding of the physical properties and chemical composition of stars.
  • D. Salpeter initial mass function
    The Salpeter initial mass function is a foundational mathematical description in astrophysics that specifies how many stars of different masses form in a given stellar population, characterized by a power-law distribution favoring low-mass stars.
  • E. An Introduction to the Study of Stellar Structure
    An Introduction to the Study of Stellar Structure is a foundational astrophysics monograph by Subrahmanyan Chandrasekhar that rigorously develops the theory of the internal structure and evolution of stars.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
