Spinning stars as stellar clocks
Spinning stars offer a useful way of determining the ages of star clusters
Are There Age Spreads in Intermediate Age Clusters?
Can stellar clusters be host to multiple star formation events? The authors of today’s paper take a closer look…
The Curious Case of the Star Cluster NGC 1651
First, we’re told that all stars in a star cluster have the same age. Then, various observations tell us that they don’t. Now, we’re being told that despite those observations, star clusters might actually be single-aged after all.
Real-Time Stellar Evolution
Sometimes, stellar evolution happens on more human timescales—tens to hundreds of years rather than millions or billions.
Spinning pair-instability supernovae
How does a massive star’s rotation affect the properties of its eventual explosion?
The History of the Galactic Halo
The number and luminosity distribution of white dwarfs stars can be used to help figure out the past history of the Galactic halo.
