"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 ...

This model links supernova progenitors and binary evolution to observed mass constraints. Opacities are considered to be the source of the disagreement between theoretical solar models and ...

"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 ...

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 ...

Nova blast A large amount of lithium, one of the key elements in the chemical evolution of the cosmos, is produced by stellar explosions called novae. The findings, reported in the journal Nature ...

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 ...

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.

I.—The Evolution of Gaseous Masses. THE progress of observational astronomy has made it abundantly clear that astronomical formations fall into well-defined classes; they are almost ...

These enigmatic objects, observed in the open cluster M67, challenge our knowledge of stellar evolution and provide fresh insights into the dynamics of multiple star systems. To appreciate the ...
