For the first time, they were able to detect radio signals from a planet beyond the solar system (exoplanet), writes the science portal Phys.org.
The signs were detected by astronomers at Cornell University in the United States, and the results were published in the Dec. 16 issue of Astronomy & Astrophysics.
We present the first clue that we may have detected an exoplanet in range. “ said Jake D. Turner, one of the astronomers involved in the study. According to the expert, the signals came from one of the planets of the two-star system known as Tau Boötes, 51 light-years away.
The strength and polarization of radio signals, as well as the planet’s magnetic field, are consistent with theoretical predictions.
The researchers used a radio telescope network called LOFAR (Low Frequency Radio Antenna System) to identify the planet emitting the signals, which is called Hot Jupiter, a gas giant orbiting close to its sun.
Astronomers from the 55 Cancri and Upsilon Andromedae systems may also have detected radio signals that indicate planets.
A close examination of the magnetic field of exoplanets will reveal not only the properties of the interior and atmosphere of a given planet, but also the effects it will have on its parent star.
The condition of the magnetic shield can also determine whether life can develop in the observed celestial body.
The results of current research contribute greatly to a more detailed understanding of distant exoplanets.
