New ALMA and JWST observations reveal why Wolf–Rayet star WR 112 produces tiny dust grains, showing a bimodal grain ...

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.

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

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 ...

In a breakthrough for exoplanet science, astronomers have discovered three Earth-sized planets orbiting both stars in a compact binary system located around 190 light-years away. The system, known as ...

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 ...

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 ...

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 ...
