Solar abundance of platinum.
Three lines of neutral platinum, located at lambda 2997.98 A, lambda 3064.71 A, and lambda 3301.86 A have been used to determine the solar platinum abundance by the method of spectral synthesis. On the scale, log A(H) = 12.00, the thus-derived solar platinum abundance is 1.75 +/- 0.10, in fair accord with Cameron's value of log A(Pt) = 1.69 derived by Mason from carbonaceous chondrites and calculated on the assumption that log A(Si) = 7.55 in the sun.
