\def\d{{\rm d}}

Eddingtonova limita:

$${\d P_r\over\d R} > {\d P\over\d R}$$

gradienty jsou z�porn�, aby se * nerozlet�la p�soben�m gradientu tlaku z��en�

pro A�R

$$P_{\rm r} = {1\over c} {4\over3} \sigma T^4$$

$${\d P_{\rm r}\over\d R} = {1\over c} {4\over3} \sigma 4 T^3 {\d T\over\d R}$$

rovnice z��iv�ho p�enosu energie

$${\d T\over\d R} = -{3c\kappa L_R\over 16\sigma T^3 4\pi R^2}$$

$${\d P_{\rm r}\over\d R} = -{\kappa L_R\over c 4\pi R^2}$$

rovnice hydrostatick� rovnov�hy

$${\d P\over\d R} = -{G\rho M_R\over R^2}$$

$$L < L_{\rm Ed} = {4\pi c G M\over \kappa}$$

(tady je chyba v Mikul�kovi!)
