Resumen
Se estudió la densidad electrónica a escala global y punto a punto de las regiones H II gigantes Hubble V y Hubble X, localizadas en la galaxia NGC 6822, utilizando espectroscopia de rendija larga en el espectro visible. Los resultados obtenidos presentan por primera vez una medida de la variación espacial de la densidad electrónica de estas dos regiones H II gigantes, demostrando que poseen un comportamiento no homogéneo en su densidad a nivel local así como un régimen de baja densidad a nivel global y comprobando que la temperatura electrónica tienen una baja incidencia en su determinación.
