Using a large radio telescope network, LOU Frequency Array (LOFAR), originally based in the Netherlands, astronomers have detected circularly polarized Barsi emissions from the Tau Botis (τ Botis) system.

Tau Botis Boyts is a binary stellar system about 51 light-years away in the constellation.
It consists of a hot and young F-type star, Tau Botis A, and a small M3-type (red dwarf) star, Tau Botis B
In 1996, a hot-Jupiter exoplanet was discovered orbiting the primary star Tau Bostis.
Known as Tau Botis B, the alien Earth is about 6 times larger than Jupiter and has an orbit of 3 days and 7.5 hours.
“We are presenting one of the first indications of detecting exoplanets in the radio region,” said Dr. John Smith, an astronomer at Cornell University’s Astronomy and Carl Sagan Institute and the University of Virginia’s Department of Astronomy. Says Jack Turner.
“In the Signal Tow Boyts system, it has a binary star and an exoplanet.”
“We made the case for emissions by the planet. From radio signals and the strength and polarization of the planet’s magnetic field, this is consistent with theoretical predictions. “
“If confirmed by follow-up observations, this radio detection has opened a new window in exoplanets, giving us a fancy way to explore alien worlds decades away from light,” said Professor Ray Rayvardhana, an astronomer at the Cornell University Department of Astronomy and Carl. Sagan Institute.
Using the Loafer Radio Telescope, Dr. Turner, Professor Jayawardene and their colleagues observed three planet-hosting systems: Tau Botis, 55 Cancri and Upsilon Andromeda.
Only the Tau Boets system displayed a unique potential window to the planet’s magnetic field, a significant radio signature.
“Exoplanet’s magnetic field observation helps astronomers understand the planet’s internal and atmospheric properties, as well as the physics of star-planet interactions,” he said. Turner said.
“Like Earth, the magnetic fields of exoplanets can contribute to their potential habitat by protecting their own atmosphere from solar wind and cosmic rays and protecting the planet from atmospheric damage.”
“There remains some uncertainty that the detected radio signal came from the planet. The need for follow-up monitoring is serious, ”he said.
The results were published in the journal today Astronomy and astronomy.
