| Zusammenfassung |
| Stellar winds of cool, main-sequence stars are very tenuous and difficult to
observe. Despite carrying away only a small amount of the stellar mass, they
are important for regulating the rotation of the star and, consequently, its
activity and magnetism. As it permeates the interplanetary space, the stellar
wind interacts with any exoplanet encountered on its way, until it reaches
the interstellar medium (ISM). These interactions can result in complex
physical processes that depend on the characteristics of the wind. To better
constrain the wind characteristics, more realistic wind models that account
for factors such as stellar rotation and the complex/diverse
observationally-derived stellar magnetic field configurations of cool stars
are required. In this paper, I present a three-dimensional model of the wind
of cool stars, which adopt as boundary condition observationally-derived
magnetic maps. I also discuss how these studies are relevant for, e.g., the
characterisation of the interaction between stellar winds and planets/ISM,
and the propagation of cosmic rays. |
