Re: nincs cím

ahha szal szerinted a nap lesz a ludas az eljegesedésben.

"Az nem érti, aki a naprendszer kis porszemecskéjén ülve, nem vesz tudomást a napról. "

Nézzük mit látunk itt a porszemen csücssülve.

A nap energoa termelése a beéső core magban játszódik és innen jut a hőenergia a felszinre sugárzással és konvektiv áramlással

In a solar model, as described in stellar structure, one considers the density \scriptstyle\rho(r), temperature T(r), total pressure (matter plus radiation) P(r), luminosity l(r) and energy generation rate per unit mass ε(r) in a spherical shell of a thickness dr at a distance r from the center of the star.

Radiative transport of energy is described by the radiative temperature gradient equation:

{\mbox{d} T \over \mbox{d} r} = - {3 \kappa \rho l \over 64 \pi r^2 \sigma T^3},

where κ is the opacity of the matter, σ is the Stefan-Boltzmann constant, and the Boltzmann constant is set to one.

Convection is described using mixing length theory[5] and the corresponding temperature gradient equation (for adiabatic convection) is:

{\mbox{d} T \over \mbox{d} r} = \left(1 - {1 \over \gamma} \right) {T \over P } { \mbox{d} P \over \mbox{d} r},
