Comparison of observed solar whole-disk oscillation frequencies with the predictions of a sequence of solar models
Abstract
It is noted that solar models computed under a consistent set of assumptions, and calibrated to the present luminosity and radius, usually depend on one or more parameters. A one-parameter sequence of models is considered here, each model being labeled by its initial heavy-element abundance Z. Given Z, the helium abundance Y and the mixing length used in the convection formulas are fixed by the calibration. An additional constraint is required to determine Z. Use is made here of the whole-disk five-minute oscillation data as a guide.
