Turner and his team have already begun a campaign using multiple radio telescopes to follow up on the signal from Tau Boötes.Speed up, tune up, and optimize your Windows PC The need for follow-up observations is critical," he said. "There remains some uncertainty that the detected radio signal is from the planet. We went searching for it and we found it," Turner said. ![]() "We learned from our own Jupiter what this kind of detection looks like. ![]() Those results became the template for searching radio emission from exoplanets 40 to 100 light-years away.Īfter poring over nearly 100-hours of radio observations, the researchers were able to find the expected hot Jupiter signature in Tau Boötes. Two years ago, Turner and his colleagues examined the radio emission signature of Jupiter and scaled those emissions to mimic the possible signatures from a distant Jupiter-like exoplanet. "The magnetic field of Earth-like exoplanets may contribute to their possible habitability," Turner said, "by shielding their own atmospheres from solar wind and cosmic rays, and protecting the planet from atmospheric loss." Observing an exoplanet's magnetic field helps astronomers decipher a planet's interior and atmospheric properties, as well as the physics of star-planet interactions, said Turner, a member of Cornell's Carl Sagan Institute.Įarth's magnetic field protects it from solar wind dangers, keeping the planet habitable. ![]() Only the Tau Boötes exoplanet system-about 51 light-years away-exhibited a significant radio signature, a unique potential window on the planet's magnetic field. The group also observed other potential exoplanetary radio-emission candidates in the 55 Cancri (in the constellation Cancer) and Upsilon Andromedae systems. Using the Low Frequency Array (LOFAR), a radio telescope in the Netherlands, Turner and his colleagues uncovered emission bursts from a star-system hosting a so-called hot Jupiter, a gaseous giant planet that is very close to its own sun. "If confirmed through follow-up observations," Jayawardhana said, "this radio detection opens up a new window on exoplanets, giving us a novel way to examine alien worlds that are tens of light-years away." From the strength and polarization of the radio signal and the planet's magnetic field, it is compatible with theoretical predictions."Īmong the co-authors is Turner's postdoctoral advisor Ray Jayawardhana, the Harold Tanner Dean of the College of Arts and Sciences at Cornell, and a professor of astronomy. We make the case for an emission by the planet itself. "The signal is from the Tau Boötes system, which contains a binary star and an exoplanet. "We present one of the first hints of detecting an exoplanet in the radio realm," Turner said. Turner, Philippe Zarka of the Observatoire de Paris-Paris Sciences et Lettres University and Jean-Mathias Griessmeier of the Université d'Orléans published their findings in the forthcoming research section of the journal Astronomy & Astrophysics, on Dec.
