An article published in the journal “Astronomy & Astrophysics” reports a study of V407 Cygni, the first known gamma-ray nova, discovered in 2010. A team of researchers led by Marcello Giroletti from the Italian National Institute of Astrophysics used data collected using the European VLBI Network (EVN) over 16 different periods to monitor the radio emissions of what is a symbiotic nova. The result was the discovery of shock waves generated by the explosion of materials accumulated on the white dwarf’s surface that forms a couple with a red giant from which it steals them.
