Nature: Wirbelsturm um Roten Riesenstern entdeckt

(PresseBox) (Wien, )
AstronomInnen der Universität Wien haben gemeinsam mit einem internationalen ForscherInnenteam eine überraschende Beobachtung gemacht: Mit Hilfe von ALMA, dem weltweit leistungsfähigsten Radioteleskopsystem, entdeckten sie eine gigantische Gasspirale um den sterbenden Stern R Sculporis. Ein bislang unerkannter Begleitstern verwirbelt die vom Roten Riesen ausströmende Materie. Die Ergebnisse stellen die ForscherInnen in der aktuellen Ausgabe des renommierten Fachjournals "Nature" vor.

Franz Kerschbaum und Claudia Paladini vom Institut für Astrophysik untersuchen den Roten Riesen schon längere Zeit mit dem Weltraumteleskop Herschel und dem ESO Very Large Telescope. Sie haben so mit ihren Vorbeobachtungen zur aktuellen Studie beigetragen.
