Multi-wavelength observations of Proxima Centauri
B. Fuhrmeister, S. Lalitha, K. Poppenhaeger +5
We report simultaneous observations of the nearby flare star Proxima Centauri with VLT/UVES and XMM-Newton over three nights in March 2009. Our optical and X-ray observations cover…
Multiwavelength observations of a giant flare on CN Leonis III. Temporal evolution of coronal properties
Carolin Liefke, Birgit Fuhrmeister, Juergen H. M. M. Schmitt
Stellar flares affect all atmospheric layers from the photosphere over chromosphere and transition region up into the corona. Simultaneous observations in different spectral bands…
Coronal properties of the EQ Peg binary system
C. Liefke, J. -U. Ness, J. H. M. M. Schmitt +1
The activity indicators of M dwarfs are distinctly different for early and late types. The coronae of early M dwarfs display high X-ray luminosities and temperatures, a pronounced…
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…
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…
Rapid magnetic flux variability on the flare star CN Leonis
A. Reiners, J. H. M. M. Schmitt, C. Liefke
We present UVES/VLT observations of the nearby flare star CN Leo covering the Wing-Ford FeH band near 1mu with high spectral resolution. Some of the FeH absorption lines in this ba…
