Proper Motions and Brightness Variations of Nonthermal X-ray Filaments in the Cassiopeia A Supernova Remnant
Daniel J. Patnaude, Robert A. Fesen
We present Chandra ACIS X-ray observations of the Galactic supernova remnant Cassiopeia A taken in December 2007. Combining these data with previous archival Chandra observations t…
The Radio Emission, X-ray Emission, and Hydrodynamics of G328.4+0.2: A Comprehensive Analysis of a Luminous Pulsar Wind Nebula, its Neutron Star, and the Progenitor Supernova Explosion
Joseph D. Gelfand, B. M. Gaensler, Patrick O. Slane +3
We present new observational results obtained for the Galactic non-thermal radio source G328.4+0.2 to determine both if this source is a pulsar wind nebula or supernova remnant, an…
Particle Acceleration in Supernova Remnants and the Production of Thermal and Nonthermal Radiation
Donald C. Ellison, Daniel J. Patnaude, Patrick Slane +2
If highly efficient, cosmic ray production can have a significant effect on the X-ray emission from SNRs as well as their dynamical evolution. Using hydrodynamical simulations incl…
Small-Scale X-ray Variability in the Cassiopeia A Supernova Remnant
D. J. Patnaude, R. A. Fesen
A comparison of X-ray observations of the Cassiopeia A supernova remnant taken in 2000, 2002, and 2004 with the Chandra ACIS-S3 reveals the presence of several small scale features…
Chandra Observations of the Luminous, O-Rich SNR in the Irregular Galaxy NGC 4449
D. J. Patnaude, R. A. Fesen
An analysis of a 29 ksec Chandra ACIS-S observation of the young, Cassiopeia-A like supernova remnant in the irregular galaxy NGC 4449 is presented. The observed 0.5-2.1 keV spectr…
An Isolated, Recently Shocked ISM Cloud in the Cygnus Loop SNR
D. J. Patnaude, R. A. Fesen, J. C. Raymond +3
Spatially resolved ROSAT X-ray and ground-based optical data for the southwestern region of the Cygnus Loop SNR reveal in unprecedented detail the very early stages of a blast wave…
Heavy Element Diffusion in Metal Poor Stars
Brian Chaboyer, W. H. Fenton, Jenica E. Nelan +2
Stellar evolution models which include the effect of helium and heavy element diffusion have been calculated for initial iron abundances of [Fe/H] = -2.3, -2.1, -1.9 and -1.7. Thes…
