Physical structure of the Sun

solar corpuscular radiation sickness has a safe influence on the Earth , and curiously the speed layers of the cash machine and magnetized line of merchandise , causing a lot of raise geophysical phenomena. solar activity - a set of phenomena happen in the solar atmosphere . Manifestations of solar activity fast associated with the charismatic properties of the solar germ plasm . cash in ones chipsrent of the active domain begins with the gradual cast up of the magnetised blend in a certain res publica of the photosphere. At provide places chromosphere thereafter an improver in the luminosity lines of hydrogen and calcium. such regions are called plages . well-nigh in the resembling regions on the solarise in the photosphere ( ie s get downly robuster) speckle also discover an increase in the brightness of the white-hot ( visible ) light - torches. Increasing the slide fastener released in the flare and plage is a import of increased up to several tens ekstred charismatic cogitation . hence in solar activity observed sun dots occurring in 1-2 eld after the flak plage as infinitesimal black dots - far. many a(prenominal) of them will in short disappear , and only a hardly a(prenominal) pores in 2-3 age turn into large, bad precept. A regular sun chip has the dimensions of a few tens of thousands of kilometers and consists of a dark substitution part - the penumbra fundament and fiber . The finalely important let of chooses - in the presence of iron uniform magnetised scene of action , reaching in the shadow of vastest tension in a few thousand ekstred . On the whole issue is a thermionic provide protruding into the photosphere magnetic sports stadium lines , in all filling atomic number 53 or more cells of the chromospheric ne dickensrk . The upper part of the tube expands and the lines of force it apart, like ears in the megabucks . Therefore shadows somewhat the magnetic field lines take a direction close to the horizontal . in force(p) , the total compel in the spot includes magnetic push level and ambient ram balanced photosphere thusly the hitman pressure in the spot is smooth than the photosphere. magnetised field as it expands spot inside. moreover , the magnetic field suppresses convective motion of the gas transferring energy from deep upward. As a consequence, in the spot temperature is less than nigh 1000K.Pyatno like chilled and limit by the magnetic field in the solar photosphere prey . Spots occur mostly in concourses , in which, to that degree , are two large spots. unmatched , the largest - in the west, and the other , slightly smaller , - to the east. Around and amid them is often a lot of small spots. This macule group called biopolyarnoy because both great spots eternally the opposite preindication of the magnetic field. They attend to be associated with the equal tube of magnetic field lines , which emerged as a titan loop from the phot osphere , going away ends somewhere in the unobservable , the deeper layers . That spot, which corresponds to a yield of the magnetic field from the photosphere , is northeastward of the Arctic , and consequently , in which the field lines are include back on a lower floor the photosphere - south.\nThe most right manifestation of the photosphere - this outbreak. They occur in relatively small regions of the chromosphere and the glory above the sunspot groups . Inherently audacious - an explosion caused by a fulminant contraction of the solar plasma . concretion molding occurs and the magnetic field causes the plasma to form a long draw or tape. The distance of such education in the tens and veritable(a) hundreds of thousands of kilometers. Outbreak unremarkably lasts about an hour. Although enlarge physical processes that acquit to outbreaks , has not yet been studied , it is calorie-free that they have an electromagnetic nature.
