Hopkins Ultraviolet Telescope Observations of Her X - 1
We have obtained a far-ultraviolet spectrum of the X-ray binary Hercules X1/HZ Herculis using the Hopkins Ultraviolet Telescope aboard the Astro-1 space shuttle mission in 1990 December. This is the first spectrum of Her X-1 that extends down to the Lyman limit at 912 Å. We observed emission lines of OVIλλ 1031.9, 1037.6, NVλλ 1238.8, 1242.8, and C IVλλ 1548.2, 1550.8, and the far UV continuum ...
متن کاملXmm-newton Epic Observations of Her X-1
We present spin-resolved X-ray data of the neutron star binary Her X-1. We find evidence that the Iron line at 6.4 keV originates from the same location as the blackbody X-ray component. The line width and energy varies over both the spin period and the 35 day precession period. We also find that the correlation between the soft and hard X-ray light curves varies over the 35 day period.
متن کاملHst Uv Observations of the Disk a N D W I N D of V795 Her
HST UV observations of V795 Her reveal a strong 2.6-h orbital variation in the prominent UV lines, in contrast to earlier (IUE) evidence of a 4.8-h period. Only the Civ line contains a strong blue-shifted, wind formed absorption component. Several lines exhibit a 'narrow' absorption feature near rest velocity which may originate in the disk, and a blue-shifted emission feature which accounts fo...
متن کاملLetter to the Editor X-ray observations during a Her X-1 anomalous low-state
Results of a 1999 July 8–10 BeppoSAX observation during an anomalous low-state of Her X-1 are presented. The standard on-state power-law and blackbody continuum model is excluded at high confidence unless partial covering is included. This gives a power-law photon index of 0.63±0.02 and implies that 0.28 ± 0.03 of the flux undergoes additional absorption of (27±7)×1022 atom cm−2. 11% of the obs...
متن کاملExpression of heregulin, phosphorylated HER-2, HER-3 and HER-4 in HER-2 negative breast cancers.
A significant number of HER-2 amplified breast cancers is effectively treated by trastuzumab and further shows receptor-enhanced chemosensitivity. Recent studies have postulated transactivation of HER-2 also in tumors expressing phosphorylated/activated HER-2 (pHER-2) and of the HER-3/HER-4 ligand heregulin (HRG), independent of HER-2 amplification. As a consequence, a subset of tumors without ...
