Using the Very Large Telescope (VLT), astronomers have discovered a compact binary system consisting of two white dwarfs in the center of a nearby globular cluster designated NGC 6397. The finding was ...

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...

Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of ...

What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

Astronomers have uncovered an extraordinary discovery in the cosmos: a binary star system consisting of two white dwarf stars, located just 150 light-years away from Earth. These stars are on a ...

Astrophysicists from MSU (Russia) and his colleagues from Italy and Russian Academy of Sciences have found the first observational evidence for a contracting white dwarf. Constant high spin-up rate of ...

These tiny layers let carbon from the core reach the surface through semi‑convective mixing. The envelope structure, combined with the low carbon abundance, fits only a rare white dwarf merger origin.

An astronomer from the University of Warwick is to investigate an intriguing type of star system to help drive our understanding of the expanding universe. Dr Ingrid Pelisoli, has received a £1.2 ...
