Phosphorus in the Young Supernova Remnant Cassiopeia A
Bon-Chul Koo, Yong-Hyun Lee, Dae-Sik Moon +2
Phosphorus (P), which is essential for life, is thought to be synthesized in massive stars and dispersed into interstellar space when these stars explode as supernovae (SNe)…
Grain Destruction in a Supernova Remnant Shock Wave
John C. Raymond, Parviz Ghavamian, Brian J. Williams +4
Dust grains are sputtered away in the hot gas behind shock fronts in supernova remnants, gradually enriching the gas phase with refractory elements. We have measured emission in C…
EUV and X-Ray Observations of Comet Lovejoy (C/2011 W3) in the Lower Corona
Patrick I. McCauley, Steven H. Saar, John C. Raymond +2
We present an analysis of EUV and soft X-ray emission detected toward Comet Lovejoy (C/2011 W3) during its post-perihelion traverse of the solar corona on December 16, 2011. Observ…
Collisionless shocks in partly ionized plasma with cosmic rays: microphysics of non-thermal components
A. M. Bykov, M. A. Malkov, J. C. Raymond +2
In this review we discuss some observational aspects and theoretical models of astrophysical collisionless shocks in partly ionized plasma with the presence of non-thermal componen…
Collisional and Radiative Processes in Optically Thin Plasmas
Stephen J. Bradshaw, John C. Raymond
Most of our knowledge of the physical processes in distant plasmas is obtained through measurement of the radiation they produce. Here we provide an overview of the main collisiona…
An Integral View of Fast Shocks around Supernova 1006
Sladjana Nikolić, Glenn van de Ven, Kevin Heng +5
Supernova remnants are among the most spectacular examples of astrophysical pistons in our cosmic neighborhood. The gas expelled by the supernova explosion is launched with velocit…
