Scientists Discover Huge Wave Energy in Highly Magnetized Sun’s Plasma Maintains Million-Degree Corona

Varanasi, Uttar Pradesh India: 

Using the world’s largest solar telescope, the 1.6 m Goode Solar Telescope at the Big Bear Solar Observatory, Dr. Ding Yuan from HIT, Shenzhen, China and science team membersdetected numerous dark features in a big sunspot by analyzing the observations made on 14th July 2015. These dark features are plasma fibrils aligned with a strong magnetic field at kilo-Gauss at the sunspot. The fibrils oscillate transversely, which means this is a kink MHD wave and they are able to drag the kilo-Gauss magnetic field lines to move laterally. It implies that the fibril kink oscillations could potentially provide a very strong energy flux. Science team has developed a mathematical model of fast kink waves in sunspots and estimated that the energy flux  is 1000 to 10000 times stronger than energy losses in active region plasma. This is sufficient to maintain the atmosphere of the Sun at a million degree Kelvin temperature.

These novel scientific results, accompanied by the first ever high resolution view of sunspot umbra, and high energy wave dynamics in its plasma fibrils are published in the prestigious Nature Astronomy Journal on 25th May 2023.

Dr Abhishek Kumar Srivastava

The globally acclaimed solar and heliospheric physicist in Indian Institute of Technology (Banaras Hindu University), Dr. Abhishek Kumar Srivastava is the part of this investigation, who played a significant role in framing the scientific works. He said that this new scientific discovery will change the view of strongly magnetized plasma regions at the Sun as it was never seen before, and will play a significant role in solving the most outstanding coronal heating problem. It will also be an outstanding scientific result for the next generation solar telescopes, and a ready reference to the laboratory plasma experiments where scientists are trying to confine the plasma and generate the green energy for the benefits of mankind.

He further informed that the sun is powered by nuclear fusion of hydrogen at the core, where the temperature reaches 16,000,000 degrees Celsius. At the visible surface (or photosphere) of the sun the temperature drops to about 5,800 degrees Celsius. It is intuitive that the hydrogen gas located further away from its core should be cooler. The corona is more distant from the core than the photosphere, but its temperature reaches millions of degrees. No current theory could explain this counter-example, this is called the coronal heating problem, a century-long challenge to physicists.
