Staring into the dramatic corpse of a dead star known as Cassiopeia A, astronomers using NASA's NuSTAR X-ray telescope have for the first time mapped out radioactive titanium in a supernova.

Not exact matches

But not only the spatial distributions of titanium and iron resemble those in Cas A. Also the total amounts of these elements, their expansion velocities, and the velocity of the neutron star are in amazing agreement with those of Cas A. «This ability to reproduce basic properties of the observations impressively confirms that Cas A may be the remnant of a neutrino - driven supernova with its violent gas motions around the nascent neutron star,» concludes H. - Thomas Janka.

Using elaborate computer simulations, a team of researchers from RIKEN in Japan and the Max Planck Institute for Astrophysics (MPA) were able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gas remnant of a nearby supernova.
