What is the light curve?
Light curve is a graph of visible light from the stars over time used to determine the behavior of the star. The light rendering technique is important for variable stars that change the brightness of regular and unpredictable ways. Light curves can also be used to describe the action of binary stars, which are two stars traveling around them. Variable stars
can change the brightness in regular samples due to the rotation of the star or interact with other stars. Variable binary occurs because both stars move due to each other and one can block the light of the other as they move. Graphs or graphs of visible light can be made of visual observations of astronomers or computer models using digital lighting devices.
Some stars can show variable light patterns over a few years, so repeated observations are required to develop a good curve. Although astronomers can assign different light for the same starValues, light curve can be accurate because many observations are brought together and diameter. Many astronomers feel that light curves from visual observations are as accurate as computer models.
Binary star behavior can be measured using this method due to the effect called eclipse. Likewise, the moon can arrest the sun and block its light when viewed from the ground, one star of a binary couple can eclipse the other eclipse. When this happens, the visible light of the view through the telescope changes, and the light curve can be used. If eclipse behavior over time occurs over time, the data can be used to determine a period of rotation or time that requires binary stars to rotate around them.
Another use of the light curve is the observation of supernova, an exploding star. Some stars reach the point of their lives when Star with a quick collapseIt is due to gravitational forces and then explodes. The result is a large increase in visible light when stars are spreading out at high speeds and observation can be used to estimate the external speed of stars and the distance of supernova from the ground.
Supernova explosion is divided into different classes based on the way in which explosion occurs. Some stars after the explosion quickly muted, while others reach a certain level of light and remain there for some time, called the behavior of the platform. These differences would not be seen using individual observations, which can make a light curve useful for classification. Supernova classes also create various elements from chemical reactions that occur during explosions, and curves can help determine the chemical composition of the expanding stars gases and the remaining material material.
