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

The discovery of the fourth star was done through an algorithm called QUADCOR, which isolates the distinct spectral fingerprints of all four stars simultaneously. By detecting the individual signals, ...

The four-star system features three stars in stable orbits, plus a fourth at a distance equal to Jupiter's orbit around our Sun.

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 ...

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 ...

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 ...

We evolved the system up to a record-breaking 1.5 seconds of real time by using the Japanese supercomputer Fugaku." The researchers observed that following its merger, the binary neutron star system ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...

Astronomers have uncovered evidence of a rare and violent collision between two planets orbiting a star known as Gaia20ehk, located over 11,000 light-years from Earth. The unprecedented discovery, ...

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 ...
