The Lives of the Longest Lived Stars
Heavy stars live like rock stars: they live fast, become big, and die young. Low mass stars, on the other hand, are more persistent, and live longer. Fusing hydrogen slow and steady wins the stellar age-race.
On and On They Spin
Nothing sits still in our Universe. Like planets, stars rotate. The authors of this paper found certain types of stars unexpectedly display rapid rotations when they are not supposed to.
A Record-Breaking Runaway Star
A star on its way out of the Milky Way has set a new speed record. What’s the rush? Read on to find out…
Cool Stars Have Magnetic Fields Too
While the Sun is an excellent starting point in a quest to understand magnetism, the authors of today’s paper want more. They take advantage of something only relatively cool stars can have in their atmospheres to study magnetic fields: molecules in starspots.
The Closest Encounter of a Stellar Kind
70,000 years ago, a binary star passed through the outskirts of the Oort Cloud–was it the closest known stellar encounter?
Spinning stars as stellar clocks
Spinning stars offer a useful way of determining the ages of star clusters
