In view of establishing the dependence of X-ray luminosity LX or flux FX with global stellar parameters, the authors analyze a sample of 44 main sequence stars observed by the Einstein Observatory and for which data are published in the literature. It is first suggested that the convection-rotation interaction can be represented by an effective Rossby number Ro*. It is given by 1/2(vm/ΩLc), where vm is the maximum convective velocity, Ω the rotation rate and Lc the total depth of the convective zone. Relations are presented first between LX and Ro*-1.2, then between FX and Ro*-3.3. These results are compared to those empirically obtained by other authors between the K line luminosity or the X-ray flux and Ω. The relations obtained support the hypothesis of a common mechanism to generate coronal emission in main sequence stars.
