Debris Disk Around The Star Contains A 1.4 Jupiter-Mass Planet

An artist’s impression of a star’s dusty debris disk, thought to be produced when asteroids or other planetesimals collide and fragment. Astronomers studying the debris disk around the star HD 206893 have imaged a wide gap in the disk extending from about 50 to 185 au from the star. After modeling the system, they conclude it contains a 1.4 Jupiter-mass planet orbiting about 79 au from the central star. NAOJ

Debris disks around main-sequence stars are tenuous belts of dust thought to be produced when asteroids or other planetesimals collide and fragment.

They are common: more than about a quarter of all main-sequence stars have debris disks and, since these disks can be hard to detect, it is likely that the fraction is even higher.
