A Chandra X-ray Survey of Ejecta in the Cassiopeia A Supernova Remnant
Una Hwang, J. Martin Laming
We present a survey of the X-ray emitting ejecta in the Cassiopeia A supernova remnant based on an extensive analysis of over 6000 spectral regions extracted on 2.5-10" angular sca…
Non-WKB Models of the FIP Effect: The Role of Slow Mode Waves
J. Martin Laming
A model for element abundance fractionation between the solar chromosphere and corona is further developed. The ponderomotive force due to Alfven waves propagating through, or refl…
Fe XVII X-ray Line Ratios for Accurate Astrophysical Plasma Diagnostics
J. D. Gillaspy, T. Lin, L. Tedesco +6
New laboratory measurements using an Electron Beam Ion Trap (EBIT) and an x-ray microcalorimeter are presented for the n=3 to n=2 Fe XVII emission lines in the 15 Å to 17 Å range,…
The Effect of a Cosmic Ray Precursor in SN 1006?
Cara E. Rakowski, J. Martin Laming, Una Hwang +3
Like many young supernova remnants, SN 1006 exhibits what appear to be clumps of ejecta close to or protruding beyond the main blast wave. In this paper we examine 3 such protrusio…
In Situ Heating of the 2007 May 19 CME Ejecta Detected by STEREO/PLASTIC and ACE
Cara E. Rakowski, J. Martin Laming, Maxim Lyutikov
In situ measurements of ion charge states can provide unique insight into the heating and evolution of coronal mass ejections when tested against realistic non-equilibrium ionizati…
