… The intensity of a spectral line u → l from a stellar corona as a function of temperature can
then be … The only stellar corona that we can image at present is that of the Sun. Sections “…

… more than the integrated light of distant stars, so it is necessary to turn to the sun for observational
guidance in the complicated theoretical question of the origin of the stellar corona. The …

… Thus, the essence of a stellar corona is not yet accessible. It is the mass loading of magnetic
fields that has given us specific diagnostics for magnetic activity to an extent that we often …

… We investigate star-planet interaction in the framework of a magnetic field model of a
stellar corona, considering the interaction between the coronal field and that of a planetary …

Context. In the vicinity of the Sun or other stars, the motion of the coronal and stellar wind
plasma must include some amount of corotation, which could affect the dynamics of charged …

… Although one example of a stellar corona (the Sun) was … If we first approximate a stellar
corona as a quasi-homogeneous … with which to compute detailed models of a stellar corona. To …

We reanalyze spectropolarimetric data of AB Dor taken in 1996 December using a surface
imaging code that can model the magnetic field of the star as a nonpotential current-carrying …

… Figure 5) it is not evident that the origin of the X-ray emission would be a stellar corona.
The triple star system Algol (~ Per B8V+G-KIV+Am) was detected as a 2-6 keV source by …
