Super-saturation Chromospheric Emission

We investigate if the super-saturation phenomenon observed at X-ray wavelengths for the corona, exists in the chromosphere for rapidly rotating late-type stars. Moderate resolution optical spectra of ...
Investigating coronal saturation and super-saturation in fast-rotating M-dwarf stars

At fast rotation rates the coronal activity of G- and K-type stars has been observed to "saturate" and then decline again at even faster rotation rates -- a phenomenon dubbed "super-saturation".
On saturation of betatron acceleration of dust particles behind shock fronts
betatron acceleration dust particles shock fronts
2010/3/9
Possible saturation of betatron acceleration of dust particles behind strong shock fronts from supernovae is considered. It is argued that the efficiency of the nonthermal dust destruction should be s...
