The authors of today’s paper simulate in impeccable detail the first few minutes of a binary-driven hypernova (the brighter cousin of a supernova) while paying close attention to how the dynamics affect the companion neutron star. They predict several observables from the process, including what has been observed in the gamma ray burst event GRB 190829A.
Where does the dust in the universe come from? Today’s bite explains that luminous blue variables, a rare type of evolved massive star, may be the second most important producer of dust in galaxies.
