(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)
UR: Physical Properties of the Host Galaxies of Ca-rich Transients
In the latest of our #UndergradResearch series, discover how Yuxin Dong explores the origins of Calcium-rich transients, a peculiar type of supernovae
Could some short and long gamma-ray bursts have the same parents?
Today’s authors discovered a kilonova associated with a long gamma-ray burst! Read on to hear about how this might flip the gamma-ray burst world upside down.
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.
