A proposed correction to the solar abundances of carbon and oxygen utilizing new and accurate theoretical forbidden transition probabilities

Abstract

Previously published solar abundances of oxygen and carbon can be corrected to be logN(O) = 8.93 and logN(C) = 8.60 on the hydrogen log-scale when new accurate forbidden electric quadrupole transition probabilities AQ(s−1) are used. Such AQ's, based on the new atomic structure and electron correlation theory, developed recently by Sinanoglu and coworkers, are reported for the (1S0-1D2) lines of [C i], [N ii, [O i] and [O iii] and the (2P-2D) lines of [N i] and [O ii]. The available experimental values are also given for comparison.
