I wanted to know if there is a well established resource in the field of Stellar Astrophysics which is not very outdated. I have seen plenty of books at my university library but I do not know if there is a classical reference.
I am a last year undergraduate (5th year in my country, so it is like a just graduate level) with good level at mathematics.
