Vega Star Research Paper

The Vega star has many different characteristics and properties when compared to other stars. The star is a white main sequence star, meaning in is in class A. The Vega is a blue to white star with a temperature of approximately 17,000 F (9,500 C) and is already 455 million years old. It is surrounded by a large disc of dust and debris, which may be from that planetary collisions. The Vega star is 25 light years away from the earth and the mass is 2.1 times bigger than the sun’s mass. Also compared to the sun, the Vega’s rotation period is less than the sun’s rotation, the sun’s rotation period is 27 days, while the Vega’s is 12.5 hours. The fast rotation of the Vega causes a bulge to occur at it’s equator. The diameter of the Vega star
The Vega star is formed like any other star and is part of the main sequence. It is formed from a nebula, a cloud of dust and gas, which contains large amounts of hydrogen and helium. The nebula then condenses into a sphere that temperature rises because of gravity and shockwaves. This condensed nebula is called a protostar, which is defined as a sphere of gas with high temperatures. The temperature gets hot enough to fuse hydrogen into helium and this ignites the protostar into a star. Once the Vega fuses hydrogen into helium, it is considered to be a part of the main sequence. The star is balanced by the outward pressure of gravity and inward pressure of the fusion. The Vega star has high mass, meaning the star will burn fuel faster and collapse faster when compared to the sun. The Vega have a high mass has such an impact of the burning rate of the star because of the stellar balancing act, to maintain balance the outward pressure of gravity and the inward pressure from fusion in the core from hydrogen turning into helium have to be equal. The faster the hydrogen fuses into helium, the faster the star will run out of hydrogen to fuses, so fusion stop, meaning the inward pressure stops and gravity keeps pressing on the star, so the star collapses. Once the star stops fusing hydrogen to helium, it is considered to be no longer in the main sequence. The main sequence life span of the Vega star is expected to be about a billion years. The Vega star will eventually become a red giant after leaving the main sequence by the fusion in the core halting. The mass of a star determines which stages the star will go through in it’s lifespan,this star will enter the stages in the order of main sequence, red giant, white dwarf, and eventually black
