The Opacity Project
The Opacity Project (OP) refers to an international collaboration that was
formed in 1984 to calculate the extensive atomic data required to estimate
stellar envelope opacities and to compute Rosseland-mean opacities
and other related quantities.
It has involved research groups from France,
Germany, the United Kingdom, the United States and Venezuela. The state-
of-the-art atomic calculations were carried out in the close coupling
approximation using the R-matrix method. The OP team has published a
comprehensive description in the book "The Opacity Project" (Vol.1, 2,
1995, 1996), containing original papers and an extensive set of
oscillator strengths.
