Summary edit

Description
English: Observations using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an unexpected spiral structure in the material around the old star R Sculptoris. This spiral, along with the surrounding outer shell, has never been seen before and is probably caused by a hidden companion star orbiting the star. This new video shows a computer simulation of how the material is distributed around the star. It presents a series of slices through a 3D model of the surroundings of R Sculptoris. The shell around the star shows up as a circular ring that appears to get bigger and then smaller in different slices. The newly discovered clear spiral structure in the inner material is best seen about half-way through the video sequence.
Deitsch: Daten des Atacama Large Millimeter/submillimeter Array (ALMA) haben unerwartet eine Spiralstruktur in der Materie um den alten Stern R Sculptoris sichtbar gemacht. Eine derartige Struktur konnte noch nie zuvor zusammen mit einer äußeren Hülle beobachtet werden. Sie wurde vermutlich von einem unsichtbaren Begleitstern verursacht, der den Hauptstern umkreist. Dieses neue Video zeigt eine Computersimulation der Verteilung der Materie um den Stern. Man sieht eine Reihe von Querschnitten durch ein 3D-Modell der Umgebung des Sterns R Sculptoris. Sie zeigen die Hülle, die den Stern umgibt, als äußeren, kreisförmigen Ring, der größer und kleiner wird, sowie die Spiralstruktur der Materie im Innenbereich, die am besten in der Mitte der Videosequenz zu erkennen ist.
