The team studied YZ Ceti b, a potentially rocky Earth-sized world beyond our solar system.
The team has identified a prospective rocky Earth-sized world beyond our solar system - YZ Ceti b, which orbits a small red dwarf star about 12 light-years away from us.
The study was led by researchers Sebastian Pineda and Jackie Villadsen, who used observations from the Karl G. Jansky Very Large Array, a radio telescope operated by the National Radio Astronomy Observatory of the National Science Foundation in the United States. "plows" the charged material back towards the star. The magnetic field of the planet directs charged plasma back toward its star. As a result, the energetic particles come into contact with the star's magnetic field, causing an aurora to form on the star.This implies that the radio signals recorded came from the star's aurora. Researchers can estimate the strength of this planet's magnetic field by measuring the power of radio waves.
According to the authors, the study provides one of the best examples of a potential magnetic field on an exoplanet. The team is planning to conduct further follow-up work to confirm the actual source of radio waves.

Do Earth-like exoplanets have magnetic fields? Far-off radio signal is promising signEarth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly blasted out of the sun. Researchers have now identified a prospective Earth-sized planet in another solar system as a prime candidate for also having a magnetic field—YZ Ceti b, a rocky planet orbiting a star about 12 light-years away from Earth.
