Betelgeuse, Betelgeuse, Betelgeuse: Is it (Supernova)time?
Will Betelgeuse go supernova in the next few decades? This paper suggests so…
Burps and explosions: What happens when a very, very massive star goes supernova?
What if you take the biggest, most massive stars, and watch them explode? Do they look any different from a normal supernova? Let’s find out with today’s supernova iPTF14hls!
UR: Matching Supernova Progenitors to their Fingerprints
In the latest of our #UndergradResearch series, Mckenzie Ferrari compares real optical supernova spectra to models to identify their progenitors.
Did a Cannonball create Sgr A East?
How was the closest supernova remnant to the galactic core created? Sgr A East is young, mysterious and could even tells the story of its origin. Perhaps we’ve already observed the stellar corpse left behind by the explosion which created the remnant.
The Continued Hunt for the Neutron Star at the Heart of SN 1987A
I spy with my little eye a pulsar wind nebula at the heart of SN 1987A. Check out today’s bite to see the latest results in the search for SN 1987A’s compact object.
Minutes after Death, Reincarnation Can Begin
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.
