A White Dwarf’s Surprise Planetary Companion

Foretelling one possible (distant!) future for our own Solar System, a giant exoplanet has been discovered orbiting close to a white dwarf star. This discovery shows that it is possible for Jupiter-sized planets to survive their star’s demise and settle into close orbits around the remaining stellar ember, near the habitable zone.

Super-Jupiter Discovered in Kepler-88 System

A team of astronomers using the Keck Observatory on Maunakea have discovered a planet three times the mass of Jupiter in a distant planetary system. This new planet, named Kepler-88 d, is the most massive planet in the Kepler-88 system, and takes 4 years to orbit around its central star. The astronomers show that, analogous to the role Jupiter plays […]

Astronomers Study the Formation of “Failed Stars”

A team of astronomers has used the Keck and Subaru telescopes on Maunakea to gain new insight into the processes of star and planet formation. They observed 27 star systems with planet-scale objects in orbit around them, by using specialized techniques to separate the light from the parent star and the much-dimmer orbiting objects. Some of the orbiters were giant […]
