The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view. However, Cheng and colleagues observe ...

Astronomers have reported observations of a rare star system consisting of one star orbiting a system of three more tightly ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Astronomers have identified a star called PicII-503 inside the ultra-faint dwarf galaxy Pictor II, and its chemical ...

Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of years ago. The star is surrounded by a ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

This Collection features original research on the mechanisms driving star formation, the lifecycle of various stellar types, and the complex interactions between stars and their environments. The ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...
