This illustration shows a hot Jupiter orbiting so close to a red dwarf star that the magnetic fields of both interact, producing activity on the star. Astrophysicists have used that activity to ...

Signals from star-planet interactions tell of strong magnetic fields in 'hot Jupiters'. Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own ...

Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the ...
