Cette propriété permet de donner la transformée de FOURIER d’une fonction retardée en fonction de la trans- formée de FOURIER du signal initial et d’un terme de retard : x(t t0)* X(f)e j2ˇft0: À nouveau, cette propriété s’obtient directement en utilisant la définition de la transformée :

We now want to see the implications of degeneracy for stellar structure. But first, it is useful to draw back and get an overview of the conditions we might encounter inside stars and where different “equations of state” (i.e., the P = P(ρ,T) relationship) will apply. 1.1. Equations of State in the T-ρ Plane

Characteristics of Main Sequence Stars

Through equations (18.8), (18.10), and (18.11), we can compute the how luminosity of a main sequence star changes with time, i.e., dL dt = µ dL dµ ¶µ dµ dX ¶µ dX dt ¶ (18.12) where dL dµ = ψ µ L0 µ0 ¶µ µ µ0 ¶ψ−1 (18.13) and dµ dX = −5 4 (3+5X)2 = − 5 4 µ2 (18.14) Putting it all together, the expression for L becomes dL ...

A Concise Introduction to Astrophysics

– Einstein’s general theory of relativity (1916) provided the first consistent basis to study cosmology. – The “Great Debate” in 1920 was concerned about the question “Does the Milky Way represents the whole Universe or is it just one island among many others?” Opik, Shapley and Hubble showed that the latter is true.¨
