A stellar four-beat waltz

- EN - FR
A system composed of four gravitationally bound stars has been followed by spectroscopy for several years by a team of researchers. This quadruple system is unstable and simulations of its future evolution show that, eventually, the stars may collide, which is likely to produce a thermonuclear supernova. The evolution of such stellar quadruple systems thus represents a new way to explain the observations of supernovae
