The research was led by Kristina G. Kislyakova, a Senior Scientist with the Department of Astrophysics at the University of Vienna, the deputy head of theAstrospheres are the analogs of our Solar System’s heliosphere, the outermost atmospheric layer of our Sun, composed of hot plasma pushed by solar winds into the interstellar medium . These winds drive many processes that cause planetary atmospheres to be lost to space .
In short, this means that the winds from these stars are much stronger than our Sun’s, which could result from the stronger magnetic activity of these stars.
