Testing Hydrodynamic Models of LMC X-4 with UV and X-ray Spectra
B. Boroson, T. Kallman, J. M. Blondin +1
We compare the predictions of hydrodynamic models of the LMC X-4 X-ray binary system with observations of UV P Cygni lines with the GHRS and STIS spectrographs on the Hubble Space…
Hydrodynamic Models of Line-Driven Accretion Disk Winds II: Adiabatic Winds from Nonisothermal Disks
Nicolas Antonio Pereyra, Timothy R. Kallman, John M. Blondin
We present here numerical hydrodynamic simulations of line-driven accretion disk winds in cataclysmic variable systems. We calculate wind mass-loss rate, terminal velocities, and l…
Discovery of mHz UV Quasiperiodic Oscillations in Hercules X-1
B. Boroson, K. O'Brien, K. Horne +5
Observations of the ultraviolet continuum of the X-ray binary system Her X-1/HZ Herculis with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope show quasiperio…
Recombination spectra of Helium-Like Ions
M. A. Bautista, T. R. Kallman
We calculate the recombination spectra of the He-like ions He~I, C~V, N~VI, O~VII, Ne~IX, Mg~XI, Si~XIII, S~XV, Ar~XVII, Ca~XIX, and Fe~XXV. We include the following physical proce…
Accretion disk models and their X-ray reflection signatures. I. Local spectra
Sergei Nayakshin, Timothy R. Kallman
X-ray illumination of accretion disks is an invaluable diagnostic of the structure of these disks because of the associated iron K emission. Here we point out that the resulting…
