The role of stellar envelope convection in gravity-darkening and its relation to observational data

Observational evaluations of gravity darkening for close binary systems, in general, are still inconclusive, due to the strong correlation between β and other parameters characterizing the light curve shape, particularly in the scale photometric 'ellipticity' effects. It is possible that very precise light curves that may be obtained in the future will allow this situation to be improved. The general surface distribution of emergent flux in the far infra-red of Jupiter may be a pointer in the direction of future studies of the subject.
