What is Flare Star?

Flare stars, also known as variables or UV CETI variables, are red dwarf stars that experience large fluctuations in surface temperature and sun flow in hours or even minutes. Flare stars are highly unpredictable, but it is amazing to watch, because most stars, such as those in the main sequence, experience the variability of their solar production only over time over time. Because the stars of the red dwarf have only a few tenths of the sun, they have less gravity and the flares are capable of energy from eating material from the star surface.

When the ignition goes out, the surface temperature can rise from 3000 K to 10,000 K in just minutes. This occurs during magnetic re -connection events. The material that is made by a star, plasma, responds to magnetic fields generated by a star. Usually, the patterns of plasma flow is in line with magnetic fields. Occasionally magnetic fields do not work into a lower energy state and dramaticallyThey regroup their configuration. Plasma plunges into a new configuration, collides with each other and heats thousands of degrees in this process. Because the stars of the red dwarf are usually relatively cold, a huge outburst of heat and energy is very noticeable. Some sun eruptions on Flare Stars are so huge that they project 20% discount on the surface of the star with respect to its diameter.

The nearest star on the ground except the Sun, Proxima Centauri, is light. Because the red dwarves are very weak in their nature, we can only observe the less than 50 years from Earth from Earth, so all stars of flares are similarly close. The most famous is UV CETI, discovered in 1948.
