(Phys.org)—Astronomers using the Atacama Large Millimeter/submillimeter Array have discovered a totally unexpected spiral structure in the material around the old star R Sculptoris. This is the first time that such a structure has been found around a red giant star. It is also the first time that astronomers could get full three-dimensional information about such a spiral. This work is one of the first ALMA early science results to be published.
