'Cool' stars are warmer and less unique than thought

Scientists from Rice University conducted simulations and found that “cool” stars (such as the Sun

) differ in the dynamic behavior of the surface.It is this that influences their energy and magnetic environment. Such stellar magnetic activity may signal that a particular star has planets that are capable of supporting life. The scientists' findings were published in the Astrophysical Journal.

Researchers have modeled what they look likedistant stars, based on the limited data available. The spin and flux of some stars were determined, as well as their classification (types F, G, K and M), which gave information about their sizes and temperatures.

In a new study, astronomers foundthat stars become less active over time, as can be seen with the Sun. According to them, it was more active in the past and this influenced the early chemical composition of the Earth's atmosphere. 

The researchers also used developed forThe sun models to other stars, testing how they adapt to them. It turned out that the “space weather” of each star works in much the same way, affecting the conditions on the corresponding planets. Scientists have also found that the processes by which a magnetic field is created may be similar in “cold” stars. The study authors note that this is “surprising and unusual.”
