A deep XMM-Newton X-ray observation of the Chamaeleon I dark cloud
J. Robrade, J. H. M. M. Schmitt
Methods. The northern-eastern fringe of the Chameleon I dark cloud was observed with XMM-Newton, revisiting a region observed with ROSAT 15 years ago. Centered on the extended X-ra…
Simultaneous optical and X-ray observations of a giant flare on the ultracool dwarf LP412-31
B. Stelzer, J. H. M. M. Schmitt, G. Micela +1
Cool stars are known to produce flares probably as a result of magnetic reconnection in their outer atmospheres. We present simultaneous XMM-Newton optical V band and X-ray observa…
The coronal Ne/O abundance of alpha Centauri
C. Liefke, J. H. M. M. Schmitt
Recent improvements in the modeling of solar convection and line formation led to downward revisions of the solar photospheric abundances of the lighter elements, which in turn led…
XMM-Newton X-ray spectroscopy of classical T Tauri stars
J. Robrade, J. H. M. M. Schmitt
We present results from a comparative study of XMM-Newton observations of four classical T Tauri stars (CTTS), namely BP Tau, CR Cha, SU Aur and TW Hya. In these objects coronal, i…
