摘要：

Improved calculations of continuous absorption from free-free transitions of the negative carbon ion are made with continuum orbitals computed with configuration interaction target atom wave-functions. We fit the absorption coefficient to a simple analytical expression suitable for stellar atmosphere opacity computations. © Royal Astronomical Society.
