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!
(almost) No Time (for stars) to Die
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!
Could Companion Stars Cause Stripped-Envelope Supernovae?
How do you make a supernova without hydrogen and helium lines? The answer may surprise you! (It’s probably binary stars)
Interpreting The Relics of Stellar Burials
The authors of today’s paper seek to uncover what is occulted in the final moments of a massive star’s death. To this end, they outline the feasibility of measuring the background flux of “relic neutrinos” and connect them to their origins.
Type II Supernovae are H0t on the Trail
Type Ia supernovae’s dimmer cousin, type II supernovae, take a shot at measuring the Hubble constant.
Transient Butterflies: Fast Blue Optical Transients can be powered by Jet-Shocked Cocoons
FBOTs or butterflies? Today’s paper presents a new model to describe the emission from fast blue optical transients.
