Magnetism disrupts winds on ‘hot Jupiter’ exoplanet

Simulations of HAT-P 7b’s magnetic field give clues to the world’s variable gusts

simulation of magnetic fields on HAT-P 7b

COLORED LINES  In this simulation of HAT-P 7b’s magnetic field lines, strong lines are shown in blue and magenta. Weaker lines are green and yellow. These magnetic field lines influence winds on the distant world, making them blow both east and west, a new study says. The stronger the lines, the wilder the winds.
