B. P. Wakker, B. D. Savage, T. A. Oosterloo +1
We present an analysis of high-resolution HI data of one of the cores of HVC187 Wakker & van Woerden 1991), HVC287+22+240. Structure is present down to the lowest-measurable scale…
Progressive covering in dipping and Comptonization in the spectrum of XB1916-053 from the BeppoSAX observation
M. J. Church, A. N. Parmar, M. Balucinska-Church +3
We report results of a BeppoSAX observation of the low-mass X-ray binary (LMXB) dipping source XB 1916-053. The source joins the small group of LMXB detected at energies ~100 keV.…
Isotopic composition of Hg and Pt in slowly rotating HgMn stars
S. Hubrig, F. Castelli, G. Mathys
Preliminary results from a study of the isotopic compositions of the elements Hg and Pt in a number of HgMn stars are presented. This work represents an improvement over previous s…
High resolution imaging of the X-ray afterglow of GRB970228 with ROSAT
F. Frontera, J. Greiner, L. A. Antonelli +6
We report results of a ROSAT High-Resolution Imager (HRI) observation of the X-ray error box given by the BeppoSAX Wide Field Camera for the gamma-ray burst that occurred on 1997 F…
