On the definition and use of grey opacities in radiative transfer problems

Transport Theory and Statistical Physics, 1971
Abstract The general problem of reducing a frequency-dependent radiative transfer problem to an equivalent grey problem is discussed. In particular, we construct, from the integral transport equation, an asymptotic solution to be used in forming grey opacities.

Theoretical isochrones from models with new radiative opacities

1994
In this paper we present large grids of theoretical isochrones for the initial chemical compositions [Z=0.0004, Y=0.23], [Z=0.004, Y=0.24], [Z=0.008, Y=0.25], [Z=0.02, Y=0.28], and [Z= 0.05, Y=0.352] and ages in the range 4 10(6) yr to 16 10(9) yr. These isochrones are derived from stellar models computed with the most recent radiative opacities by ...
