The signal was observed by the European Loafer Radio Telescope, a network of 50,000 antennas spread across Europe and operating at very low frequencies, the energy sector not yet exploited.
The show comes from our organization Theophilus, located 50 solar years away, which is the “immediate suburb” of our solar system. It contains a double star and a nearby gas giant Exoplanet: “Hot Jupiter” known as Theophitis-B.
The mass and orbit of many exoplanets were already known, but until now there is no way to know whether they have a magnetic field or not. We see this shield, protecting it from the radiation of the stellar wind, around the Earth, and “our” Jupiter.
However, Philippe Sarca of the Paris Laboratory explains that the radio broadcast captured by Loafer is “the most accurate signature of the magnetic field” – BSL, one of the leading authors of the study published this week in astronomy and astronomy.
These waves are very difficult to detect, the planetary magnetic fields are generally weak and far from their emission.
So the international team that conducted the research looked at three extrasolar systems (thebody, 55 Congregation and Ups) that contain gas giants, which may be powerful emitters because they are so close to their star.
Taking the radio signal from our Jupiter as a sample, the analysis of a maximum of one hundred hours of observation begged in support of the expected signature of the boutique.
“The signal has a 98% chance of being reliable,” said Philip Sarka, who remains a little skeptical about the possibility of the signal emanating from its star, not from the planet itself. “To be really sure, it takes 99.9% chance. We have to continue the observations, which is within our range,” says the astronomer.
If the emission is true, “this is the first time that a radio detection technique has been confirmed, and therefore a step towards the nature of exoplanets,” the researcher underscores.
First, 51 Pekasi B, nearly 4,000 exoplanets have been discovered since they were discovered 25 years ago.
Philip Sarka says that having a magnetic “bubble” around them is an ingredient that is favorable to “habitat”, that is, conducive to the growth of a kind of life. But there are other criteria such as temperature, in this case the boutique b. Life is too hot to shut down.
