High Resolution X-ray Spectroscopy of Pre-Main-Sequence Stars: TWA 5 and PZ Tel
C. Argiroffi, J. J. Drake, F. R. Harnden +5
We report on the analysis of high resolution X-ray spectra of two pre-main-sequence stars: TWA 5 (observed with XMM-Newton) and PZ Telescopii (observed with Chandra/HETGS). TWA 5 i…
Multiwavelength study of X-ray emitting A- and B-stars testing the companion hypothesis
B. Stelzer, N. Huelamo, S. Hubrig +3
We report on the first results of a multi-wavelength approach to test the hypothesis that the X-ray emission from intermediate-mass stars is generated by late-type magnetically act…
X-ray emission and variability of young, nearby stars
B. Stelzer, R. Neuhaeuser
X-ray emission has played a major role in the recent identification of several groups of young, nearby stars. The ROSAT All-Sky Survey (RASS) is due to its spatial completeness an…
X-ray emission from young stars in the Tucanae association
B. Stelzer, R. Neuhaeuser
We report on X-ray emission from members of the recently discovered Tucanae association, a group of stars with youth signatures and similar space motion. The Tucanae association is…
