Further X-ray detections of Herbig stars
B. Stelzer, J. Robrade, J. H. M. M. Schmitt +1
The interpretation of X-ray detections from Herbig Ae/Be stars is disputed as it is not clear if these intermediate-mass pre-main sequence stars are able to drive a dynamo and ensu…
Quiescent X-ray emission from the M9 dwarf LHS 2065
J. Robrade, J. H. M. M. Schmitt
We investigate an archival XMM-Newton observation of LHS 2065, an ultracool dwarf with spectral type M9. We clearly detect LHS 2065 at soft X-ray energies in less than 1 h effectiv…
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…
X-rays from RU Lupi - Accretion and winds in CTTS
J. Robrade, J. H. M. M. Schmitt
Using three XMM-Newton observations we study the X-ray emission of RU Lup, a accreting and wind-driving CTTS. In comparison with other bright CTTS we study possible signatures of a…
