Do convection currents and vibrating magnetic field lines create the dynamic phenomena observed on the Sun?
According to the thermonuclear fusion model of the Sun, hydrogen in its core is crushed with so much force that it is converting to helium, releasing tremendous amounts of energy. The core’s temperature is thought to be 15 million Celsius, with compressive strain greater than 340 billion times Earth’s atmospheric pressure. A common metaphor used to illustrate the process is to imagine millions of hydrogen bombs exploding all at once within a confined space: 700 million tons of hydrogen are said to be converted into helium every second.
The Sun’s surface is known as the photosphere. Above that surface layer is the chromosphere, and above that is the corona, the outermost part of the Sun’s visible atmosphere. The photosphere averages 6000 Celsius, while the corona can be as much as two million Celsius! This is the great mystery that has encumbered researchers. How is it that the hottest region of the Sun begins at an altitude of 4000 kilometers and extends over a million kilometers from its surface without any significant temperature drop?
Many ideas have been proposed for how this steep temperature rise occurs. Some research groups have concluded that it is the “rearrangement of magnetic field lines,” otherwise known as “magnetic reconnection,” that is causing the heating. Both the SOHO and TRACE satellite observatories have detected small, rapidly changing magnetic regions on the Sun’s surface.
