JAKARTA – Astronomers at the New Jersey Institute of Technology’s Solar Terrestrial Research Center (NJIT-CSTR) announced an extraordinary discovery regarding bursts of radio waves on the Sun.
For the first time, NJIT-CSTR discovered radio emissions that appear similar to aurora, a phenomenon of light emitting in the Earth’s northern hemisphere at night. This emission is formed 40,000 kilometers above the sun.
According to a report by NJIT-CSTR Scientist Sijie Yu, this incident originates from sunspots, which are areas of the sun that are very dark and cold. This emission was a polarized radio burst that lasted for more than a week.
“This is very different from temporary solar radio bursts that usually last a few minutes or hours. “This is an exciting discovery that has the potential to change our understanding of stellar magnetic processes,” Yu was quoted as saying BUTTER from the NJIT website.
According to his team’s findings, Yu said that this radio emission was formed because the sun’s magnetic field lines were so strong. It’s just that the emissions are different from usual, both from the wavelength category to the duration of endurance.
“Unlike auroras on Earth, these sunspot aurora emissions occur at frequencies ranging from hundreds of thousands of kHz to around 1 million kHz, a direct result of the sunspot magnetic field which is thousands of times stronger than the Earth’s magnetic field,” said Yu.
Through the results of these observations, astronomers can conduct research by linking the behavior of the sun and the magnetic phenomena around it. The results of this research could make physicists rethink the current state of magnetism in stars.
“We are starting to piece together the puzzle of how energetic particles and magnetic fields interact in a system with the long-lasting presence of star spots, not only on our Sun, but also on stars far beyond our solar system,” explains Yu.
