The Coronal X-ray Spectrum of the Multiple Weak-Lined T Tauri Star System HD 98800
Joel H. Kastner, David P. Huenemoerder, Norbert S. Schulz +3
We present high-resolution X-ray spectra of the multiple (hierarchical quadruple) weak-lined T Tauri star system HD 98800, obtained with the High Energy Transmission Gratings Spect…
Chandra/ACIS Subpixel Event Repositioning. II. Further Refinements and Comparison between Backside and Front-side Illuminated X-ray CCDs
Jingqiang Li, Joel H. Kastner, Gregory Y. Prigozhin +3
We further investigate subpixel event repositioning (SER) algorithms in application to Chandra X-ray Observatory (CXO) CCD imaging. SER algorithms have been applied to backside ill…
Refining Chandra/ACIS Subpixel Event Repositioning Using a Backside Illuminated CCD Model
Jingqiang Li, Joel H. Kastner, Gregory Y. Prigozhin +1
Subpixel event repositioning (SER) techniques have been demonstrated to significantly improve the already unprecedented spatial resolution of Chandra X-ray imaging with the Advance…
On the Asymmetries of Extended X-ray Emission from Planetary Nebulae
Joel H. Kastner, Jingqiang Li, Saeqa D. Vrtilek +3
Chandra X-ray Observatory (CXO) images have revealed that the X-ray emitting regions of the molecule-rich young planetary nebulae (PNs) BD+30 3639 (BD+30) and NGC 7027 are much mor…
Infrared Space Observatory Polarimetric Imaging of the Egg Nebula (RAFGL 2688)
Joel H. Kastner, Jingqiang Li, Ralf Siebenmorgen +1
We present polarimetric imaging of the protoplanetary nebula RAFGL 2688 obtained at 4.5 microns with the Infrared Space Observatory (ISO). We have deconvolved the images to remove…
