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…
Testing evolutionary tracks of Pre-Main Sequence stars: the case of HD113449
F. Cusano, E. W. Guenther, M. Esposito +3
Evolutionary tracks are of key importance for the understanding of star formation. Unfortunately, tracks published by various groups differ so that it is fundamental to have observ…
Direct evidence of a sub-stellar companion around CT Cha
T. O. B. Schmidt, R. Neuhäuser, A. Seifahrt +5
In our ongoing search for close and faint companions around T Tauri stars, we found a very faint (Ks=14.9mag, Ks_0=14.4mag) object, just ~2.67" northwest of the Chamaeleon star-for…
The stellar content of the Hamburg/ESO survey. IV. Selection of candidate metal-poor stars
N. Christlieb, T. Schoerck, A. Frebel +3
We present the quantitative methods used for selecting candidate metal-poor stars in the Hamburg/ESO objective-prism survey (HES). The selection is based on the strength of the Ca…
