Two puzzling astronomical objects are white dwarfs formed by mergers of less massive white dwarfs, the discoverer of both claims, but they have curious features that suggest they represent a new class ...

Astronomers at Michigan State University and the University of Michigan have teamed up on research that's taken the highest-resolution images to date of star explosions called novae (the plural of ...

Astronomers have uncovered the violent secret of V Sagittae, a white dwarf star consuming its companion in a spectacular feeding frenzy. This cosmic dance not only makes the system burn with unusual ...

This small carbon trace marks this object as a product of a rare white dwarf merger rather than single‑star evolution. In a paper published in Nature Astronomy, Snehalata Sahu (University of Warwick) ...

A research team has successfully imaged a nova in high resolution—and the images suggest that the nova was not a single, impulsive explosion. A nova is an astronomical phenomenon that occurs in a ...

Researchers have used stellar evolution simulations to trace the future of ATLAS J1138-5139, an ultra-compact double white ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

Astronomers recently peered deep into space and found that an old, faint white dwarf named LSPM J0207+3331, located about 145 light-years away, is still consuming the rocky remains of its former ...
