dc.description.abstract | The colour difference between the star and the attendant reflection nebula and polarization both caused by silicate and graphite grains have been given. The properly normalized size distribution function for each type of grains has been considered within homogeneous plane parallel slab-model of the reflection nebula with the star in the rear. Contrary to some earlier results, it has been possible to show that silicate grains can certainly play a role in the phenomena of reflection nebulae. | en |
dc.description.abstract | [Translated Abstract] Die durch Silikat- und Graphitteilchen verursachte Farbdifferenz zwischen einem Stern und dem zugehörigen Reflexionsnebel sowie die Polarisation werden angegeben. Die geeignet normalisierte Verteilungsfunktion der Teilchengrößen für jeden Partikeltyp wird in einem homogenen planparallelen Schichtmodell eines Reflexionsnebels mit dem leuchtanregenden Stern im Hintergrund diskutiert. Im Gegensatz zu einigen früheren Ergebnissen war es möglich nachzuweisen, daß Silikatteilchen durchaus eine Rolle in den Reflexionsnebeln spielen können. | - |
