Why is the temperature of the corona so high?

The light of the corona comes from the outermost side of the sun, and it is actually wrong to say that the corona is hot, the temperature of the corona is not very high, if you must say that the temperature is high, it is because the heat of the corona comes from the sun.

It is affected by the magnetic field formed in the depths of the sun. Unlike heat conduction, the process of magnetic field action is not limited by the principle of thermodynamics, and energy can reach the outermost part of the high temperature from a lower surface.

The main reason is that the temperature of the sun is very high, and nuclear fusion reactions are taking place all the time.

The spectrum of the Sun is the absorption spectrum, so the temperature of the Sun's atmosphere is lower than that of the photosphere.

So far away from the solar core, why is the coronal temperature so high? The answer remains a mystery to this day.

The real reason for the corona's abnormally high temperature should be that the momentum of high-energy particles is not conserved. The energy of high-energy particles close to the surface of the sun is compressed, and once ejected away from the surface of the sun, the excess energy inside the high-energy particles will overflow, thus forming a coronal layer with a temperature of millions of degrees.

This is the same principle as springs. The conjecture theories of Alven waves, magnetic currents, plasma currents, etc., which heat the coronal layer, cannot explain the low temperature of the chromosphere and photosphere under the coronal layer. If it is the latter conjectures, the color field and the photosphere layer should also have bands of high temperatures.

1. Corona. The layer temperature can reach 1 million degrees Celsius.

The solar corona refers to the outermost layer of the Sun's atmosphere (its interior is the chromosphere and the photosphere), which is more than a few million kilometers thick. Beyond the chromosphere is the coronal layer, which is extremely hot, with a temperature of 1 million degrees Celsius.

2. The temperature of the chromosphere is 4,600k tens of thousands of degrees from the inside to the outside.

The chromosphere is in the solar atmosphere.

However, there is an abnormal distribution of temperature inside. Within the chromosphere, which is about 2,000 kilometers thick, the temperature increases from 4,600 K at the top of the photosphere to tens of thousands of degrees at the top of the chromosphere, while some other physical parameters such as density, ionization.

etc.), and some physical processes have also changed dramatically. Therefore, the study of the physical condition of the chromosphere has attracted a lot of attention from solar physicists.

3. The temperature of the photosphere is 5500 degrees.

Although the ball of light is bright as a whole, the brightness of the parts of the limbs is very uneven. , the undisturbed photosphere is covered with rice grains, the total number is estimated to reach 4 million, and in the active area of the photosphere, there are sunspots.

Flares of light and occasionally flares of white light.

Their brightness, physical state and structure are very different, and the average undisturbed photosphere emits a radiation rate of Erg per square centimeter per second, from which the effective temperature of the photosphere can be calculated to be 5500 degrees.

There is a coronal hole in the corona, which is the source of the solar wind. The sunset is seen only when there is a range of foods during the day, and its shape changes with the size of the sun. In solar activity, the shape of the sunset is close to circular, and the solar activity is oval.

How is the corona on the surface of the Sun formed?

The corona is the outermost layer of the Sun's atmosphere (inside which are colored and photospheres) and is millions of kilometers thick. Outside the colored sphere is the sunset layer, which is very high, the coronal temperature is very high by 1 million degrees Celsius, and the number of particles is 1015 square meters.

The corona is the outermost layer of the sun's atmosphere, extending from the edge of the colored sphere to several solar radii and beyond. Divided into internal, intermediate and external definitions, the inner line extends only to the surface of the sun about times the radius of the sun; The front shape can reach several solar radii and even more. Sunlight consists of very thin completely ionized plasma, mainly protons, highly ionized ions, and high-speed free electrons.

The corona can be divided into internal pools, intermediate and external distinct. The inner line extends from the top of the ball to a multiple of the radius of the sun; The middle is a multiple of the radius radius to a multiple of the radius of the sun, and some people collect times of the radius of the sun. The radius of the sun is more than a multiple, which is called the external definition (from above the distance from the heart).

An overview can include the extent to which the solar wind can achieve.

The coronal temperature is 1 million degrees Celsius and the particle count is 1015 square meters. At high temperatures, hydrogen, helium and other atoms are already ionized with positively charged protons, helium nuclei and negatively charged free electrons. These charged particles are very fast, so the charged particles keep increasing the sun's gravity and shoot at the perimeter of the sun.

Formation of solar wind. The light decolorization of the sunset is also weak.

The corona is mainly composed of high-speed free electrons, protons, and highly ionic (plasma). Its material density is less than 2 10-12 kg m3 and the temperature is high. Due to the low temperature and low density of the corona, it is very weak and is in a state of non-local thermal equilibrium, in addition to visible radiation, there are radiative radiation, X-rays, ultraviolet rays, long-hair radiation and high ionic ions.

The coronal temperature is 1 million degrees Celsius. The corona is the outermost layer of the Sun's atmosphere, extending outward from the edge of the chromosphere to several solar radii and beyond. It is divided into an inner, middle and outer corona, and the inner corona extends only about a distance from the surface of the sun; The outer crown can reach several r's lengths, or even more.

The corona is composed of very thin completely ionized plasma, which consists mainly of protons, highly ionized ions, and high-speed free electrons.

The core of the sun is a high-temperature furnace with temperatures of up to 15 million Kelvin, which decreases as far as the surface layer increases, while the corona can reach temperatures as high as 1 million to 3 million Kelvin. Because between the chromosphere and the corona there is a "transition zone" with a thickness of from ten to hundreds of kilometers, where the temperature suddenly rises. It is difficult to explain this phenomenon from a thermodynamic point of view.

And if you want to cross the corona, you won't feel its heat. Although it is very hot, it is very thin.

The temperature can reach 15 million Kelvin, and the temperature is particularly high because the sun releases a lot of heat from the surface of the sun, and then it hits the corona.

More than 2 million. Because the reaction in the outer layer is more violent, the temperature is higher, while the inner temperature is lower.

。Why is the corona so hot? This remains a mystery to this day.

It has been explained that strong sound waves are stirring everywhere inside the sun, and waves of certain energy escape from the surface of the sun, thus impacting the corona, which absorbs the energy of the wave and makes it warmer. The same goes for chromospheres.

Recent research suggests that the corona's high temperature may be caused by coronal material absorbing electromagnetic energy from the sun's surface.

Even the flames of the earth are higher than the inner flames. The laws of physics are sprinkled

Why is the coronal layer of the sun the hottest.

The temperature of the solar corona can reach as high as 1 million degrees Celsius, and in some areas it can reach 2 million degrees Celsius. The cause of coronal heat is said to be due to the fact that the momentum of high-energy particles is not conserved. The distance of the energetic particles from the solar field will release their excess energy, forming a hot region and thus accelerating the formation of the solar wind.

If you think of a high-energy particle as a spring, then the particle on the surface of the sun is the spring that is being squeezed, and once it is out of the extrusion range of the force field, it will release the extruded energy and form a new equilibrium.
