Pierre LГ©na, FranГ§ois Lebrun, FranГ§ois Mignard, "Observational Astrophysics"
This second edition has been entirely restructured and almost doubled in size, in order to improve clarity and account for the great progress achieved in the field over the last 15 years. This is not a handbook for observers. It is a broader reference for students, active researchers, and anyone who wants a detailed look at the tools of modern astronomy.
