Theoretical solar models [PDF]

open access: yesSymposium - International Astronomical Union, 1997
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling.
