The snack that fights back
Today’s bite explores how munching on tiny black holes can lead stars to an early demise.
Preparing students for astronomy beyond the classroom
In today’s (Beyond) bite, I describe a new course at Columbia University that aims to equip undergrads with foundational research skills.
Speedy stars reveal a satellite’s supermassive secret
By rewinding the orbits of hypervelocity stars, today’s authors discover something unusual about the Milky Way’s largest satellite galaxy.
Watch out! There’s double-faced white dwarfs about
How can one white dwarf have two different atmospheres? Today’s authors investigate the wacky behavior of ZTF J2033 to find out.
AGB stars can have a little PIE, as a treat
Proton ingestion events in AGB stars are thought to trigger i-process nucleosynthesis. Today’s authors construct detailed stellar models to investigate this phenomenon!
