Resumen:
Abstract. We solve the equation of hydrostatic equilibrium for the photosphere of B stars with magnetic elds including a term for the Lorentz force and the radiative force. We analyze the formation of chemically anomalous concentrations in the stellar surfaces, particularly, we focusing our attention on the diffusion of helium.We solve the equation of hydrostatic equilibrium for the photosphere of B stars with magnetic elds including a term for the Lorentz force and the radiative force.
