Full core-to-surface profiles of stars can be found in various scientific databases, such as the NASA Exoplanet Archive, the European Space Agency's Gaia archive, or the Harvard-Smithsonian Center for Astrophysics database.
No, full core-to-surface profiles are typically only available for stars that have been well-studied and have enough observational data to create a comprehensive profile.
Full core-to-surface profiles of stars are created by analyzing various types of observational data, such as photometric and spectroscopic measurements, and using models and algorithms to map out the internal structure of the star.
Yes, most scientific databases that host full core-to-surface profiles of stars are freely accessible for anyone to use.
While full core-to-surface profiles of stars can provide valuable insights into the internal structure of a star, they are not always 100% accurate due to the complexity and variability of stars. These profiles are constantly being refined and updated as new data and techniques become available.
