Multiwavelength observations of a giant flare on CN Leonis I. The chromosphere as seen in the optical spectra
B. Fuhrmeister, C. Liefke, J. H. M. M. Schmitt +1
Flares on dM stars contain plasmas at very different temperatures and thus affect a wide wavelength range in the electromagnetic spectrum. While the coronal properties of flares ar…

Localizing Plages on BO Mic, First steps towards chromospheric Doppler imaging
U. Wolter, J. H. M. M. Schmitt
We have obtained a densely sampled time series of CaII H&K line profiles of the ultrafast rotating K-dwarf star BO Mic. Taken at high resolution, the spectra reveal pronounced vari…

Spectroscopic analysis of a super-hot giant flare observed on Algol by BeppoSAX on 30 August 1997
F. Favata, J. H. M. M. Schmitt
We present an X-ray observation of the eclipsing binary Algol, obtained with the BeppoSAX observatory. During the observation a huge flare was observed, exceptional both in duratio…
