Two young stars whirling around each other in a vast cloud of dust known as the Pipe nebula are weaving a pretzel-like tapestry as their gravity warps surrounding material into twisted loops and swirls, part of a two-step feeding frenzy.
Taking advantage of the Atacama Large Millimeter/submillimeter Array’s high resolution, an international team of astronomers has captured a spectacular image of what’s been dubbed a “cosmic pretzel,” revealing the inner structure of the binary star system.
“We see two compact sources that we interpret as circumstellar disks around the two young stars,” said Felipe Alves, a researcher who led the study for the Max Planck Institute for Extraterrestrial Physics. “The size of each of these disks is similar to the asteroid belt in our solar system, and the separation between them is 28 times the distance between the Sun and the Earth.”
Co-author Paola Caselli called the research “a really important result.”
“We have finally imaged the complex structure of young binary stars with their ...
