Scientists explain what causes plasma bursts in the sun's atmosphere
Researchers from India and the UK say that convection in the lower atmosphere, such as a vessel of boiling water, hits the plasma in the sun's chromosphere.
Using laboratory experiments as an analogy, researchers from India and the United Kingdom (UK) have explained how plasma, the fourth form of matter, appears in one of the three atmospheric layers of the sun's chromosphere like rays called spicules.
The consensus is that the physics behind the shorter needle is different from the higher and faster hand. However, the new study challenges this widely held belief and shows that the sun's convection can form all kinds of radiation.
The study of spicules is of great interest to plasma astrophysicists because they can explain the process of sending plasma into the solar wind and heating the sun's atmosphere to one million degrees Celsius.
Led by astronomers from the Indian Institute of Astrophysics, an interdisciplinary team of researchers from India and the UK has discovered that the physics behind color rays, when excited by loudspeakers, are similar to solar plasma rays.
The researchers show that the model in which the jets are fired resembles the color of a bass speaker.
If the liquid is placed over the subwoofer and music is turned on above a specific frequency, the liquid-free surface becomes unstable and vibrate. However, paint or shampoo-like liquids cause a continuous glow when the speaker is excited because the long polymer chains determine the direction.
The article's authors admit that the physics underlying this color emission should be analogous to solar plasma emission. However, they found that the glow remained intact against instability caused by the solar magnetic field and, therefore, by polymer chains in polymer solutions.
Sahel Day of the Indian Institute of Astrophysics (IIA), and first author of the study, said in a statement: "Solar plasma can be visualized as intersecting magnetic field lines, like long chains in the polymer solution. This makes both systems anisotropic, with properties varying in size. direction."
"Inspired by the visual similarity between the sun's needle and the color rays on the speaker, we investigated the role of the magnetic field on the sun using numerical simulations of solar plasma. In parallel, we studied the role of polymer chains using slow-motion video," said Murthy OVSN, co-author of Azim Premji University.
