They are very bright, although their surface temperature is lower than that of the Sun.Red giants have diameters between 10 and 100 times that of the Sun.Proxima Centauri, the nearest star to the Sun, is a red dwarf.According to some estimates, red dwarfs make up three-quarters of the stars in the Milky Way.They are quite small compared to the sun and have a surface temperature of about 4000 ֯C.Because of their low luminosity, they are not visible to the naked eye.The faintest (less than 1/1000 th the brightness of the Sun) main sequence stars are called the red dwarfs.Towards the end of its life, a star like the Sun swells up into a red giant, before losing its outer layers as a planetary nebula and finally shrinking to become a white dwarf.Most of the stars in the universe - about 90 per cent of them - are main sequence stars.Main sequence stars are stars that are fusing hydrogen atoms to form helium atoms in their cores. A very young, lightweight star, less than 10 million years old, that it still undergoing gravitational contraction it represents an intermediate stage between a Protostar and a low-mass main sequence star like the Sun.Protostars are usually surrounded by dust, which blocks the light that they emit, so they are difficult to observe in the visible spectrum.The luminosity comes exclusively from the heating of the Protostar as it contracts (because of gravity).That is why it is hard to achieve and control). Nuclear fusion occurs only when the initial temperatures are very high – a few million degree Celsius. A Protostar looks like a star, but its core is not yet hot enough for nuclear fusion to take place ( nuclear fusion: the fusion of 2 hydrogen atoms into a helium atom with the liberation of a huge amount of energy.A nebula is a cloud of gas (mostly hydrogen and helium) and dust in space.White dwarf (in case of a small star) and Neutron Star or Black Hole (in case of a large star).Planetary Nebula (in case of small star) and Supernova (in case of large star).Red Giant (in case of a small star) and Red Supergiant (in case of a large star).Sun – full of life (nuclear fusion at the core at full swing). Protostar: an early stage of a star formation where nuclear fusion is yet to begin.Outlined below are the many steps involved in a star’s evolution, from its formation in a nebula, to its death as a white dwarf or a neutron star.System Requirements of Star Drift Evolution Game Want to play ” Dead Space 3 Game ” Please hit the Download.
