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.
Guide to Transient Astronomy
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!
A Beginners Guide to Predicting Supernovae
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.
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.
Cosmic Coughs: The Dust Production of Luminous Blue Variables
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.
