Dr. Kerstin Weis "Plasmas around Stars"

The next lecture in the series All Plasma was given by Dr. Kerstin Weis on the topic "Plasmas around Stars".

The motivation for the topic was described as follows: When we look into the cloudless sky at night, the stars all appear to us as whitish points of light - yet they are very different. The celestial bodies differ in mass, surface temperature and color. The sun is also a star, and - like all other stars - it consists of hot plasma. Stars, however, not only emit light, but also steadily emit plasma: as stellar wind or solar wind. Under certain conditions, the stellar wind can become visible as a colorful nebula surrounding the star.
