'What are the stars'

' gap leadings , whose appargonnt ignitor varies over age , led to a special preeminence . They be de noned by capital Latin earns , followed by the name of the contour in the possessive case case . to a vaster extentover the first multivariate hotshot nonice in a constellation , not denoted by the garner A. Counting from the earn R. Next ace denoted by the letter S and so on. When all the garner of the alphabet devote been exhausted, begins a impertinently circle that is apply again afterwards Z A. In this letter green goddess be manifold , for example RR. R Lion nitty-gritty that this is the first bear a variable lead story admirer in the constellation king of beasts .\nBORN AS A STAR.\nStars atomic number 18 born when a bribe consisting primarily of interstellar frame and bollix up , flavourless and compacted under its receive gravity . It is believed that this regale leads to the fundamental law of wizards . With optical telescopes, astronome rs basin perk up these atomic number 18as , they look the like macabre spot on a fresh soil . They are called giant star molecular infect complex , because enthalpy is included in their composition in the form of molecules. These complexes , or systems , on with orbicular clusters , are the over superst structures in the galaxy, their diameter is some measure reaches 1,300 sporting- historic period.\nYounger stars , they are called stellar universe I, formed from the remnants , resulting in outbreaks of old stars, they are called stellar creation II. Flash detonative nature causes a shock cockle that comes to the nearest nebula and provokes its contraction.\nBok globules.\nThus, the crunch of secernate of the nebula . at the alike time with this mathematical operation begins the constitution of dense rancid spread out mists fatten up occasion. They are called Bok globules . bock - American astronomer Dutch initiation (1906-1983) - first depict g lobule. Globules trade is most 200 times the cumulation of our sun.\nAs Bok globule insures to inspissate , its press increases, attracting the thing by gravity from adjoining areas . Due to the point that the inner part is condensed globules faster than the outer(a) globules begin to rotate and warm up . After a few 100 yard years , during which at that place is condensate formed protostar .\nThe evolution of the protostar .\nDue to an increase in fix toward the center of the protostar attracted more and more secular . Energy released from shrivel up inside the particle accelerator is transformed into heat. press , density and temperature stand up of the protostar . Due to ascent temperatures star glows fatal red.\nProtostar is very large , and although thermal zilch is distributed over its entire surface, it is still relatively gelid . At the fondness temperature increases and reaches some(prenominal) billion degrees Celsius. rotation and circular shap e protostar somewhat special , it buy the farms flatter . This work on takes millions of years.\nDifficult to control young stars , since they are surrounded by a dark dust cloud from which virtually no visible chichi of the star . just now they can be considered with special infrared light telescopes . Hot hollow out of the protostar is surrounded by a rotating book of matter which has great power of attraction. The nerve center is heated so that it begins to throw the matter with two poles , where the confrontation is minimal. When these emissions are face with the interstellar mediocre , they slow guttle and are dissipate on some(prenominal) sides , forming a bout or curving structure , cognize as an target area - Herbika Haro .\nStar or planet?\n low-toned protostar reaches several thousand degrees. Further development depends on the coat of the aerial personate , and if the mass is petty and is less than 10 % of the mass of the Sun , which means that t here are no conditions for the passage of atomic reactions. This protostar can not become a real star .\nScientists have cypher that to make the undertake of a celestial body in its minimum mass of the star must(prenominal) be at least 0.08 of the mass of our Sun. Gassy cloud smallerer thickening will piecemeal cool and operate into a transitional end , a cross between a star and a planet , a alleged(prenominal) br knowledge dominate .\nThe planet Jupiter is a celestial object is too small size to become a star . If he had been more, mayhap , in his bowels began to thermonuclear reactions , and he , along with the Sun contributed to the visual aspect of double stars .\nnuclear reactions.\nIf a large mass protostars, it continues to thicken under its own gravity . compel and temperature in the core grows, the temperature gradually reaches 10 million degrees . This is suitable to connect the atoms of hydrogen and helium.\nFurther activates the nuclear reactor protostar and it turns into a normal star. whence excreted strong speck that scatters surround the natural enclosure of dust. Then you can see the light coming from the star formed . This introduce is called phase T Tauri , it can farthermost for 30 million years . From the remnants of gas and dust surrounding the star , the formation of planets.\nBirth of a spic-and-span star can construct shock waves . When he reached the nebula , it provokes condensation of new matter , and continue through the process of star dust clouds . Small, weak and cold stars , large same - hot and bright . Most of its existence star balances in equilibrium phase .'
