One of the first snapshots of stellar evolution was done in the early 1900s. First as a data table by Ejnar Hertzsprung in 1905, but more famously done as a diagram by Henry Norris Russell in 1914.

The HR diagram is one of the most important tools in the study of stellar evolution. It is a plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus ...

Using 3-D models run on some of the fastest computers in the world, laboratory physicists have created a mathematical code that cracks a mystery surrounding stellar evolution. Using 3D models run ...

"J0524-0336 contains 100,000 times more lithium than the sun does at its current age. This amount challenges the prevailing models of how stars evolve." Astronomers have discovered a new star that ...

Others form in the violent processes that mark the demise of more massive stars. Which stars form which elements, and how those elements form, is what stellar evolution and nucleosynthesis aims to ...

Described in a new study published in The Astrophysical Journal, this breakthrough offers new insights into an extreme phase of stellar evolution, and one of the biggest mysteries in astrophysics.

"This is an important step in our endeavor to understand the formation of the Milky Way and other galaxies." Scientists are building a better account of the lives of adolescent stars, starting ...

These stars' ages vary from a few million to a billion years old, depending on the group, a range that offers astronomers a sweeping view of stellar evolution among our neighbors. Gagné and ...

Black holes come in a range of sizes. Stellar mass black holes form from the collapse of massive stars, typically weighing between 5 and 100 times the mass of our sun, and are scattered throughout ...
