Mit eindimensionalen Simulationen wurde die zeitliche Entwicklung und Dynamik von Filamenten in Molekülwolken untersucht. Die Berücksichtigung von Rotation, Gaseinfall und Staub ermöglichte es, deren Einfluss auf die Entwicklung zu untersuchen. Künstliche Spektren wurden entwickelt um eine Aussage über mögliche Signaturen in den Beobachtungen von Filamenten zu machen. Ich habe eine deutliche Separierung einzelner Staubkomponenten in allen Phasen der Entwicklung entdeckt, dass auf einen rein dynamischen Effekt zurückzuführen ist. Des Weiteren sieht man, dass große Staubpartikeln hauptsächlich innerhalb des Filaments zu sehen sein sollten, während kleine Staubteilchen auch außerhalb des Filaments zu finden sind. Außerdem wurde gezeigt, dass d...
