An international team of astronomers including Stella Offner of the University of Texas at Austin has proposed a new method for the formation of aluminum-26 in star systems that are forming planets. Because its radioactive decay is thought to provide a heat source for the building blocks of planets, called planetesimals, it’s important for astronomers to know where aluminum-26 comes from. Their research is published in the current issue of The Astrophysical Journal.
