Abstract: | The comoving-frame equations of radiative transfer and moment equations to accurate terms of all orders inv/c are derived in the modified Lagrangian form. The equations exactly describe the interaction of radiation with matter in a relativistically moving medium in flat or curved spacetime. Two specialized sets of equations are presented: (1) the equation of radiative transfer and moment equations accurate to terms of second order (v
2/c
2), and (2) the transfer equation and moment equations for a radial flow in curved spacetime with the Schwarzschild-type metric. |
