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.
Today’s paper presents “echoes” coming from a supernova in the nearby galaxy Centaurus A.
Transients are some of the most variable and most explosive objects in our universe. We’ve got a great overview about all different types of transients in this guide!
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?
If the light from supernovae travels at, unsurprisingly, the speed of light (which really is the upper limit here), how can we predict them? Time travel, is that you? Spoiler alert: it isn’t. It’s neutrinos.
How long does it take for a star’s core to collapse in a supernova explosion? Today’s authors use observations to place new constraints on the explosion timescale!
