A measurement of the wind speed on a brown dwarf [PDF]

Science, 2020
High winds in an extrasolar atmosphere Brown dwarfs are objects intermediate in mass between large planets and small stars, and their atmospheres share many characteristics with gas giant planets. Wind speeds in Solar System gas giant atmospheres can be derived by comparing the planet's rotational periods in the infrared (tracing
