Abstract: | In the past few decades, large amount of knowledge about the solar corona and solar wind has been gathered by both in-situ and remote measurements all over the solar system. However, this knowledge is not fully considered in stellar astrophysics, even though it is highly relevant. In particular, mass loss of stars to their stellar winds are traditionally related to their level of activity and their X-ray flux. In the talk, I will overview the known properties of the solar wind and will show how the solar mass flux and the solar X-ray flux do not seem to correlate at all. I will also discuss the possible reason for this finding. |
