Wobbling stars reveal hidden companions in Gaia data

Using data from the European Space Agency’s Gaia mission, and the Habitable Zone Planet Finder and NEID Spectrometers developed at Penn State, scientists, including Penn State astronomers, 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 sense the gravitational tug or ‘wobble’ the planet induces on a star. Both the planet and brown dwarf are orbiting low-mass stars, a scenario thought to be extremely rare.

A full story about the research is available on the European Space Agency website.

The team included several current and former Penn State researchers, faculty members, and students.
