The sky is a bright object is large, fixed konphlatma by stellar gravity near Earth is the Sun, which is the world's main energy source. We can see another stellar night sky if there is no light from the Sun obscured. In the history of the featured star on the sky sphere will be considered together as a group of stars and the stellar brightness that is specifically named. Astronomers have stellar lists many more. To be used as a standard in the stellar names.Throughout most of the life expectancy of the stellar light emitting it because the nuclear fusion reaction of Star axis Thermo, which releases energy from the star's Interior and then onto radiation space that almost all chemicals which occur naturally and are heavier than helium have originated.From the total stellar mass may be caused by stellar Nucleosynthesis during the stars still alive or arising from Nucleosynthesis of the Super Nova after stellar explosions occurred after the end of the life expectancy. Astronomers can determine the size of the mass, chemical composition, age, and several other stellar properties observed spectrum the brightness and movement in space. Total mass of stellar evolutionary sequence is determined in principle and fate in the end of the stars. Another feature of such stellar diameter rotation. Motion and temperature is determined by its evolutionary history. Diagram coordinates between the stellar brightness temperature, lots of diagrams, also known as Hare thasot Cook-Russell (H-R diagram) Helps to identify the age and evolution of stellar models.Mobile stellar from molecular clouds that rupture, with hydrogen as the main components, including helium and other elements that are heavier than the number one. When naughty stellar density is high enough. Some hydrogen is converted to helium through nuclear fusion continues [1] section within the rest of the stellar energy is released from the hard core through the process of radiation and convection element. Internal pressure of the stellar prevent it continuing to collapse from its own gravity. When the star's hydrogen fuel all the naughty stellar mass is at least 0.4 times the Sun [2] To swell out until it becomes a red giant, which in some cases, these stars will melt the elements that are harder than hard core or in shells around the hard core of the red giant stars from the evolution to a book format with partial recycling of matter into matter between stars. These substances will cause a new version of the stellar, which is the ratio of the higher heavy element [3]Double star systems and multiple star systems, stellar lights consist of two moons or more binding together with gravity. And most often in a stable orbit khotronop When such a star system star, there are two moons in orbit around each other, too. Reaction force of gravity between stellar may impact on the evolution of them. [4] Stellar can be assembled as part of a larger structure on the binding by gravity, such as cluster or Galaxy.
