Stellar coronae and their relation to convection zones and rotation rates
Abstract
Correlations between stellar coronal properties and convection zone properties are derived using simple scaling laws and available data. It is shown that the use of term g* in the basic realtionship between the coronal emission measure Em(Tc) and coronal pressure, explains why the Em(Tc) or the Einstein X-ray fluxes should scale with the Rossby number Ro.
