| Abstract: |
In δ Scuti star models the photometric amplitudes and phases exhibit a strong dependence on convection, which enters through the complex parameter, f, that describes the bolometric flux variation. We present a new method of extracting l and f from multi color data and apply it to several δ Scuti stars. The inferred values of f are sufficiently accurate to yield a useful constraint on models of stellar convection. |
