By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new ...

The study analyzed the circumstellar disks of a pair of stars, learning about how planets are formed from some unexpected ...

Abstract: Binary star systems are assumed to be co-natal and coeval, and thus to have identical chemical composition. In this work, we aim to test the hypothesis that there is a connection between ...

The number of planets that orbit the sun depends on what you mean by “planet,” and that’s not so easy to define ...

Staring up at the night sky, you might see thousands of stars sprinkled above the horizon. It feels as though you can see so ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

The ESA’s Gaia mission mapped the positions and velocities of stars with extreme precision by measuring about one billion ...

has unveiled intriguing findings about planet formation in this binary star system, known as DF Tau, along with other systems in this region. The work is published in The Astronomical Journal.

A Triple Star System Yields an Unusual Surviving Star Unlike our Sun, which exists alone, at least half of the stars in our ...

offering valuable clues about the dynamics of binary star systems. Researchers have also noted that dust formation is not uniform, with accumulations forming delicate clouds as vast as our solar ...

Using in part the NEID spectrograph mounted on the WIYN 3.5-meter Telescope at the U.S. National Science Foundation Kitt Peak ...
