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…
Detecting X-ray Synchrotron Emission in Supernova Remnants: Implications for Abundances and Cosmic Rays
Kristy K. Dyer, Stephen P. Reynolds, Kazik J. Borkowski +1
The 10^51 ergs released in a supernova have far reaching consequences in the galaxy, determining elemental abundances, accelerating cosmic rays, and affecting the makeup of the int…
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…
Separating Thermal and Nonthermal X-Rays in Supernova Remnants I: Total Fits to SN 1006 AD
K. K. Dyer, S. P. Reynolds, K. J. Borkowski +2
The remnant of SN 1006 has an X-ray spectrum dominated by nonthermal emission, and pre-ASCA observations were well described by a synchrotron calculation with electron energies lim…
Dynamics of Fe-Ni Bubbles in Young Supernova Remnants
J. M. Blondin, K. J. Borkowski, S. P. Reynolds
Observations of core-collapse supernovae (SNe) have revealed the presence of extensive mixing of radioactive material in SN ejecta. The mixing of radioactive material, mostly fresh…
Kinematics of 1200 km/s Jets in He 3-1475
K. J. Borkowski, J. P. Harrington
Spectroscopic observations of a proto-planetary nebula He 3-1475 with the Space Telescope Imaging Spectrograph (STIS) reveal the kinematics of its high (1200 km/s) velocity jets. T…
HST Spectroscopy of Spot 1 on the Circumstellar Ring of SN 1987A
Eli Michael, Richard McCray, C. S. J. Pun +15
We present ultraviolet and optical spectra of the first bright spot (PA = 29 degrees) on Supernova 1987A's equatorial circumstellar ring taken with the Space Telescope Imaging Spec…
Supernova Remnants in the Sedov Expansion Phase: Thermal X-Ray Emission
K. J. Borkowski, W. J. Lyerly, S. P. Reynolds
Improved calculations of X-ray spectra for supernova remnants (SNRs) in the Sedov-Taylor phase are reported, which for the first time include reliable atomic data for Fe L-shell li…
Thermal X-ray Emission and Cosmic Ray Production in Young Supernova Remnants
A. Decourchelle, D. C. Ellison, J. Ballet
We have developed a simple model to investigate the modifications of the hydrodynamics and non-equilibrium ionization X-ray emission in young supernova remnants due to nonlinear pa…
A Broadband X-Ray Study of the Supernova Remnant 3C 397
S. Safi-Harb, R. Petre, K. A. Arnaud +5
We present an X-ray study of the radio bright supernova remnant (SNR) 3C 397 with ROSAT, ASCA, and RXTE. A central X-ray spot seen with the ROSAT High-Resolution Imager hints at th…
Thermal and Nonthermal X-Ray Emission in SNR RCW 86
K. J. Borkowski, J. Rho, S. P. Reynolds +1
Supernova remnants may exhibit both thermal and nonthermal X-ray emission. Such remnants can be distinguished by the weakness of their X-ray lines, because of the presence of a str…
Nonthermal Emission from a Supernova Remnant in a Molecular Cloud
A. M. Bykov, R. A. Chevalier, D. C. Ellison +1
In evolved supernova remnants (SNRs) interacting with molecular clouds, such as IC 443, W44, and 3C391, a highly inhomogeneous structure consisting of a forward shock of moderate M…
The Cosmic Ray - X-ray Connection: Effects of Nonlinear Shock Acceleration on Photon Production in SNRs
Donald C. Ellison
Cosmic-ray production in young supernova remnant (SNR) shocks is expected to be efficient and strongly nonlinear. In nonlinear, diffusive shock acceleration, compression ratios wil…
Nonlinear Shock Acceleration and Photon Emission in Supernova Remnants
Donald C. Ellison, Evgeny G. Berezhko, Matthew G. Baring
We have extended a simple model of nonlinear diffusive shock acceleration (Berezhko and Ellison 1999) to include the injection and acceleration of electrons and the production of p…
Low Frequency Insights Into Supernova Remnants
Kristy K. Dyer, Stephen P. Reynolds, Kazik J. Borkowski
Low frequency observations at 330 and 74 MHz can provide new insights into supernova remnants (SNR). We can test theoretical predictions for spectral index variations. Nonlinear mo…
New Models for X-Ray Synchrotron Radiation from the Remnant of Supernova 1006 AD
K. K. Dyer, S. P. Reynolds, K. J. Borkowski
Galactic cosmic rays up to energies of around 10^15 eV are assumed to originate in supernova remnants (SNRs). The shock wave of a young SNR like SN 1006 AD can accelerate electrons…
