Spinning stars offer a useful way of determining the ages of star clusters
Can stellar clusters be host to multiple star formation events? The authors of today’s paper take a closer look…
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.
Sometimes, stellar evolution happens on more human timescales—tens to hundreds of years rather than millions or billions.
How does a massive star’s rotation affect the properties of its eventual explosion?
The number and luminosity distribution of white dwarfs stars can be used to help figure out the past history of the Galactic halo.
