(almost) No Time (for stars) to Die

(almost) No Time (for stars) to Die

by Sahil Hegde | Jun 27, 2022 | Daily Paper Summaries

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?

Could Companion Stars Cause Stripped-Envelope Supernovae?

by Sarah Bodansky | May 26, 2022 | Daily Paper Summaries

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

Interpreting The Relics of Stellar Burials

by Lindsay DeMarchi | Apr 22, 2022 | Daily Paper Summaries

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

by Abby Lee | Apr 16, 2022 | Daily Paper Summaries

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

Transient Butterflies: Fast Blue Optical Transients can be powered by Jet-Shocked Cocoons

by Jason Hinkle | Jan 23, 2022 | Daily Paper Summaries

FBOTs or butterflies? Today’s paper presents a new model to describe the emission from fast blue optical transients.

A New Recipe for Neutron Star Magnetic Fields

A New Recipe for Neutron Star Magnetic Fields

by Ryan Golant | Nov 30, 2021 | Daily Paper Summaries

How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.
