The classification scheme for Magnetic Cataclysmic Variables (MCVs) is addressed. When only ten or twenty MCVs had been discovered their classification was simple and based on direct observational properties. Now that the number of MCVs exceeds one hundred, the method of classification needs updating. One important consideration is the possibility that binaries might physically change their classification. For example will intermediate polars become polars as they evolve to shorter orbital periods? Or does a polar become an intermediate polar when synchronism is broken due to a nova?

Resumen

Resumen

Se presenta un esquema para clasificar las Variables Cataclísmicas Magnéticas (MCVs). Cuando las MCVs descubiertas cran diez veinte fue sencillo clasificarlas basándose en sus propiedades observacionales directas. Ahora que el número de MCVs excede el centenar, el método para clasificarlas necesita ser actualizado. Una consideración importante es la posibilidad de que las binarias puedan cambiar fisicamente su clasificación, pог ejemplo ¿llegarán polares intermedias a eonvertirse en polares conforme evolucionan hacia períodos orbitales más cortos? O, ¿podrá transformarse una polar en una polar intermedia al romperse el sincronismo debido a una nova?
