Gaia-4b, a giant exoplanet orbiting a small star, is the first planet confirmed using Gaia’s astrometric technique.

Scientists using data from the European Space Agency’s Gaia mission have made a groundbreaking discovery: a massive exoplanet ...

Using data from the European Space Agency’s Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia’s ability to ...

They also confirmed that one system is a star hosting a brown dwarf—an object with a mass in between those of planets and ...

Gaia-4b is a planet orbiting the star called Gaia-4, around 244 light-years away. Gaia-4b is about twelve times more massive than Jupiter. With an orbital period of 570 days, it is a relatively cold ...

Using the Keck Planet Imager and Characterizer (KPIC), astronomers have performed high-resolution spectroscopic observations of a brown dwarf known as HD 206893 B. Results of the observational ...

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

Given the available data, we are able to constrain the inclination of the system to >81° and the orbital period to ≳40 yr. Basri, G. 1998, in ASP Conf. Ser. 134, Brown Dwarfs and Extrasolar Planets, ...
