The collision –or even a near-miss– of a neutron star and a main sequence star can possibly explain long-lived, bumpy supernovae and hypervelocity stars.
How does one measure the gravitational wave signal of a supernova if each event is unique? Is machine learning up to the task? Or is it unknowable?
Bright satellites have dire effects on the field of astronomy, indigenous religious practices life cycles, and our quality of living. Blue Walker 3 can outshine Venus in the night sky. AST plans to have 110 of these satellites by 2024.
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.
History has been made! The first magnetic field inside a main-sequence star has been measured!
