Essay: Luminosity near Star Vega

What is the brightness of a nearby star Vega? What kind of a star is it? I will describe the unit of light intensity and how to express it. How often is Vega lighter than the sun? How old do you think Vega is? Every second we move about 20 km from the current Vega position. If Vega is 26.5 L-Y (light years) away from the Earth, how long does it take for the sun (and its planet) to reach this distance? Does the sun collide with Vega? Description

Vega is a white series with a brightness of 37. Brightness is the energy released from the body per unit time. It can be measured in units of watt of SI or sunlight, ie the amount of radiant energy in the body is the brightness of the sun is 846 x 1026 W of the sun, Vega is 58 times brighter than the sun. It is bigger and brighter than the sun, its lifetime is very short. Since it is already the main sequence star, its age should be less than a billion years. To move 20 kilometers per second to Vega's current location, it takes about 286 417 years to reach it. However, since Vega is not far from us, there is no danger of collision (Lewis, 1997).

The brightness of a star is the amount of light emitted per unit time and other forms of radiant energy. It has the power of a unit. The brightness of a star depends on its radius and surface temperature. Many stars do not radiate uniformly over the entire surface. For example, a high speed rotating star vega has higher energy flux (power per unit area) than its energy flux along its equator at its pole. Plaques on the surface of stars whose temperature and intensity are lower than the average are called star spots. A small dwarf like our sun usually has discs that are essentially uncharacteristic, with only a few star points. Superstars have larger, more distinct star spots, and they are also getting dark of strong stars. That is, the brightness decreases towards the edge of the star. A red dwarf flare star like UV Ceti may also have remarkable star features

Explanation Vega is a white series main star with a brightness of 37. Brightness is the energy released from the body per unit time. It can be measured in SI units watt or sunlight intensity. That is, the number of times the body radiates energy is 3.846 × 1026 W in the sun's brightness. Vega is 58 times brighter than the sun. It is bigger and brighter than the sun, its lifetime is very short. Since it is already the main sequence star, its age should be less than a billion years.
