V745 Sco

A 3D model of an explosion from the V745 Sco system is helping astronomers learn more about this volatile system. V745 Sco is a binary system where a red giant and a white dwarf star are in very close orbit around one another. Astronomers observed V745 Sco with Chandra a little over two weeks after the 2014 outburst. Their key finding was it appeared that most of the material ejected by the explosion was moving towards us. To explain this, a team of scientists from the INAF-Osservatorio Astronomico di Palermo, the University of Palermo, and the Harvard-Smithsonian Center for Astrophysics constructed a three-dimensional (3D) computer model of the explosion, and adjusted the model until it explained the observations. In this model they included a large disk of cool gas around the equator of the binary caused by the white dwarf pulling on a wind of gas streaming away from the red giant. This 3D print was simplified and printed in two parts, the blast wave and the ejected material.
