CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe study the polarization of the UV light within the cavities of interstellar grain aggregates modeled as homogeneous spheres containing several spherical voids. The incident field is a linearly polarized plane wave.We found that field depolarization occurs in all examined cases so that the field within the cavities has the features of an elliptically polarized wave. The depolarization of the field does not depend on the material of the grains but on the geometry of the problem only. The implications of this result for the interstellar photochemistry are briefly discussed.
