Extremely accurate measurements of the position of β Pictoris from the Hipparcos and Gaia satellites allow the direct measurement of the mass of the imaged planet β Pic b.
We need to know the radii of M-dwarfs to study their exoplanets, and the models aren’t much help.
Can the properties of a known planet system predict if that system has additional undetected planets?
Are planets just as likely to form around binary stars as they are around single stars? Today’s authors are asking this very question.
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
Today’s authors search for Jupiter analogs in foreign star systems to see how these giant worlds might affect the development of planets closer to the sun.
