A coronal explosion on the flare star CN Leonis
J. H. M. M. Schmitt, F. Reale, C. Liefke +4
We present simultaneous high-temporal and high-spectral resolution observations at optical and soft X-ray wavelengths of the nearby flare star CN Leo. During our observing campaign…
Doppler imaging an X-ray flare on the ultrafast rotator BO Mic - A contemporaneous multiwavelength study using XMM-Newton and VLT
U. Wolter, J. Robrade, J. H. M. M. Schmitt +1
We present an analysis of contemporaneous photospheric, chromospheric and coronal structures on the highly active K-dwarf star BO Mic (Speedy Mic). We localize a moderate flare in…
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…
Doppler imaging of Speedy Mic using the VLT, Fast spot evolution on a young K-dwarf star
U. Wolter, J. H. M. M. Schmitt, F. van Wyk
We study the short-term evolution of starspots on the ultrafast-rotating star HD197890 ("Speedy Mic" = BO Mic, K 0-2V, P_rot = 0.380 d) based on two Doppler images taken about 13 s…
