Astronomers find a group of stars dying too early
... PhD student Mr Ben MacLean, the lead author of the paper describing these results. While current models of stellar evolution do not predict the premature demise of these types of helium-burning star, a similar pattern has been observed...

Long standing initial mass function problem solved
... power law has far-reaching implications into many branches of astronomy as the distribution of stellar masses affects the evolution of stellar clusters. If you want to understand galaxy formation, which consequently has implications for large-scale...

Binary stars and their extraordinary lives
..., many are so close that the stars interact by mass exchange during their lifetimes, significantly altering their stellar evolution. This can occur when mixing, induced by the proximity of the secondary star, transforms one of them into...

Planetary nebulae may hold clue in search of helium-3
... up. 3He - where else does it come from? Stellar evolution models predict that stars with masses less than 2.5 the...could destroy their 3He before they reach their last stages of stellar evolution. It turns out that, after lots of modifications to the...

New light shed on the mystery of 'Born Again' stars
..., stars like Aldebaran for example, but instead manifested as a blue straggler, is therefore important for testing models of stellar evolution. Other theories have also been postulated for the formation of blue stragglers and these include the...

High-Energy X-rays show Andromeda Galaxy in a different light
... that it is likely the lower-mass remnants of normal stellar evolution, the black holes and neutron stars, may play a crucial... Andromeda Galaxy in ultraviolet light taken by NASA's Galaxy Evolution Explorer and the swath of sky captured by NuSTAR. ...
