Rayon 0,7 millions km
Masse 2e30 kg
Age 4,6 miliards
Puissance rayonnement 3,8e26 W
Composition 73%(H) 25%(He) 2%(other)
Temperature 6000k ou 7000C°
Terre-Soleil ~150 millions km

E=equivalence entre masse et energie
E=m*c^2
E=energie en Joules = J = W/s
m=masse en kg
c=vitesse lumiere 3,10e8 m/s

Dm = m(final) - m(initial)
De = e(final) - m(initial)
De(E) = Dm(kg)*c^2(m/s)
Dm = De/c^2 - si Dm<0 alors DE<0
Dm*c^2 = P*Dt

De=Dm/c^2=3,8e26/3e108^2=4,22e9 kg
masse du soleil diminue 4,22e9 kg/s
puissance surfacique 1360 W/m^2
puissance soleil P = 3,85e26 W
E(J) = P(W) * Dt(s)

S = 4piR^2 = 4pi(1,5e8) = 2,82e17
De=P*Dt=3,83e26*1

Amax=long onde emission max en metres
T=temp surf corps incondescendant kelvins(K)
Loi Wien - constante = Amax*T
temp corps noir =T(K)= cste/Amax

energie fusion hydro > thermique > lumineuse
surface soleil:
4*1/1H -> 4/2He + 2*0/1e + 2v
