An international team of scientists lead by Irish astronomer Dr. Eamon O'Gorman have been awarded 32 hours of observing time with the international LOFAR array to search for radio waves from planets orbiting other stars. It is believed that billions of these so-called ‘exoplanets’ exist in our galaxy alone, and Dr O’Gorman is confident that some of them can be detected at radio wavelengths with LOFAR.
Dr O’Gorman said, “In our own solar system, Jupiter can outshine the Sun at certain radio wavelengths. We predict that some massive exoplanets should be detectable with LOFAR thanks to its groundbreaking and unparalleled sensitivity. Detecting exoplanets at radio wavelengths would not only open the door to a whole new method of their detection, but would also allow us to study their magnetic fields, composition, and how fast they rotate.”
Dr O'Gorman also explained that the proposed I-LOFAR telescope at Birr castle would be revolutionary for both the Irish astrophysics community and the entire LOFAR member states across Europe. “I-LOFAR will increase the overall sensitivity of the array and will enable us to see finer details. It will certainly improve our chances of finding these faint radio signals from other worlds. It is exciting to think that we are now close to having the capabilities of studying exoplanets from Ireland.”
