Looking for a single stellar ancestor: Mono-enriched stars in zoom-in simulations
Today’s bite explores if we’ll be able to find a star that has formed from the gas enriched by only one stellar predecessor, an interesting way to probe what’s actually happening in stellar nucleosynthesis.
The Anatomy of Active Galactic Nuclei
Active Galactic Nuclei produce some of the most dazzling fireworks in the Universe. Let’s dissect one to figure out what powers them!
